consolidate CI files, updates Ruby and Node versions (#820)
This is a PR with three key changes:

1. Consolidate two identical CI files, `ci.yml` and `ci-master.yml` into one file
2. Consolidate two almost-identical jobs (`jekyll-build-*`) into one job with a strategy matrix
3. Update various dependencies/platforms
    * Node: `12.x` -> `16.x` (only in CI); `12.x` has been EOL for a while
    * Ruby: `2.6` -> `2.7`; `2.6` just reached EOL
    * `actions/checkout` -> `v2` -> `v3`
    * switches `jekyll/builder` to `jekyll/jekyll`, since we don't actually use any of the features in `jekyll/builder`

## on our CI philosophy

In working on this, I have a couple of questions:

1. We don't actually use our `Dockerfile` that we provide. Does this make sense? Should we be running CI with this instead?
2. Is there a specific reason that we're using `jekyll/jekyll`? Notably, this isn't an official package, but a community-driven one. Does it match what's used by GitHub Pages?
3. Do we have to use any docker image at all? For example, what if we just rely on the `setup-ruby` action?
    * one advantage of this is that it's much easier for us to test across multiple OS versions; we just need to have a strategy matrix for OS and do windows, macos, ubuntu, etc.
    * another advantage is that we can easily test different ruby versions in conjunction with different jekyll versions

Eventually, I would like to see us test across:

* different Jekyll versions
* different OSes
* different Ruby versions

but perhaps that might be too aggressive. Happy for any feedback on this PR or those questions!
