v0.5.2

This follows up from #1259 and closes #1261. Basically, this PR accomplishes the two items discussed in the issue:

1. for all anchors that are *actually* buttons (i.e., have `href="#"`), I've replaced them with a semantic `<button>`
    - under the hood, I've made a `.btn-reset` class pulling out the reset from #1259, so there's no visual change
2. for anchors that are ["toggle buttons"](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/button_role#toggle_buttons) (the mobile menu nav, sidebar children/grandchildren toggles), I've added an `aria-pressed` property that is updated as the button is clicked

I've also slightly modified some of the `aria-label`s to make them more consistent. Observe that we *shouldn't* update these as the button is clicked; screen readers use the `aria-pressed` property to add an annotation to each button.

To test this,

- the sidebar children and grandchildren can be done on the deploy preview:
    - open an arbitrary page; observe that the sidebar children/grandchildren dropdown ticks now have a proper `aria-label` and `aria-pressed`, as well as otherwise work as intended
    - toggle one of the buttons; observe the `aria-pressed` role changing as this is done
    - open a grandchild page; observe that the `aria-pressed` has a correct default wrt whether or not the page is active
- the mobile menu can be done on the deploy preview; on a smaller viewport, observe the correct `aria-pressed`
- two features require local changes to test:
    - the `site.search.button` needs to be enabled in the `_config.yml`. To test this, locally clone the repo, change the flag, and observe that the button still works as intended + has no visual regressions.
    - the collections feature is a bit more complicated. To test this, locally clone the repo, add an arbitrary collection and changes to `_config.yml`, and observe the same behaviour for the sidebar children/grandchildren above

+## Release v0.5.2
+
+Hi all, this is a minor patch release that mostly focuses on accessibility. Since we follow semantic versioning, this should be a smooth upgrade with no breaking changes.
+
+In addition, the theme docs website has a new canonical URL: <https://just-the-docs.com>. We've also retroactively published the theme docs website for version `v0.3.3` at <https://v0-3-3-docs.just-the-docs.com/>. Thank you to our GitHub sponsors for funding our domain name!
+
+### Using Release `v0.5.2`
+
+Users who have not pinned the theme version will be **automatically upgraded to `v0.5.2` the next time they build their site**.
+
+To use this release explicitly as a remote theme:
+
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.5.2
+```
+
+To use this version explicitly as a gem-based theme, pin the version in your `Gemfile` and re-run `bundle install` or `bundle update just-the-docs`:
+
+```ruby
+gem "just-the-docs", "0.5.2"
+```
+
+To use and pin a previous version of the theme, replace the `0.5.2` with the desired release tag.
+

+Hi all, this is a very small minor patch release that has two small behavioral bugfixes: fixing a regression introduced in `v0.5.0` on Safari versions `<16.4` (broken media query), and the copy code button providing incorrect feedback in insecure browser contexts. This should be a smooth upgrade with no breaking changes.

We suggest that all users refer to the guide before manually upgrading their site.
 
 **For the vast majority of users, we do not anticipate that this will be a breaking change.** The major touch points are surrounding new includes, navigation (ordering, pages, and collections), the favicon, and a shift to relative URLs. However, users who heavily customize the theme (primarily by overriding includes) will likely have to make minor changes.

-  A page with `nav_exclude: true` does not appear in the main navigation.
-  If it has a `parent`, it may appear in the parent's table of contents.
-  If it specifies `has_children: true`, it should appear in the breadcrumbs
-  of the child pages, but its order in relation to other pages is irrelevant.
-  Pages that never appear can be removed from the pages that need to be sorted.
-  This optimisation can be significant on a site with many pages.
-  
-  In Jekyll 4, the pages to be sorted can be filtered by:
-  
-  {%- assign title_pages = title_pages
-        | where_exp: "item", "item.nav_exclude != true or item.parent != nil" -%}
-  
-  That filter is not allowed in Jekyll 3. The following iterative code gives the
-  same effect, but it is activated only when it will filter more than 50% of the
-  pages.

-  The order of sibling pages in `pages_list` determines the order of display of

   For example, consider the following condition:

-

   Here, `node` is a first-level page. The last part of the condition

+
+# Layout
+
+You specify the layout for a page in its [front matter]. Just the Docs has a `default` layout with a sidebar, used for almost all pages in the theme docs, and a `minimal` layout that omits the sidebar.
+{: .fs-6 .fw-300 }
+
+## The layout concept
+
+See the [Jekyll docs page about layouts] for an explanation of the general idea of layouts and how to specify them.
+
+You can use [Jekyll's front matter defaults] to specify the same layout for many pages.
+
+## The `default` layout
+
+This page uses the default layout.
+
+It is a *responsive* layout: on medium and larger width displays, it displays a sidebar, including a navigation panel; on smaller width displays, the sidebar is automatically hidden under a button.
+
+Each child (and grandchild) page of a top-level page has so-called *breadcrumbs*: links to its parent (and grandparent) pages. It shows the breadcrumbs above the main content of the page.
+
+Each page that has child pages generally has a list of links to those pages (you can suppress it by `has_toc: false` in the front matter). It shows the list as a *table of contents* below the main content.
+
+## The `minimal` layout
+
+A child and grandchild page of this page use the minimal layout. This differs from the default layout by omitting the sidebar -- and thereby also the navigation panel. To navigate between pages with the minimal layout, you can use the breadcrumbs and the tables of contents.
+
+## Other layouts
+
+Just the Docs has further layouts: `about`, `home`, `page`, and `post`. Currently, they are all based on the `default` layout. See the [Jekyll docs about inheritance] for how to customize them.
