This PR does two things: 1. fixes using mermaid version `>= 10` from the CDN, by importing the ESM module instead 2. moves script loading code from `head.html` to the mermaid include I've also added some light documentation to clarify how using mermaid with local paths should work (users should specify a version, and they should only use fully-minified bundles with no local references). The nice thing about this approach is that it's a breaking change for nobody, and only adds functionality (v10 support). Eventually, we should remove support for mermaid <10, which should make this much easier! Closes #1206. ## Context In v10, Mermaid has implemented a few (admittedly, very frustrating to deal with) breaking changes: 1. they've removed CJS support, which is fine, *but* 2. that means that the `dist` they publish to JSDelivr now has a **different URL**: for versions `10.0.0` - `10.0.2`, **they do not have a minified bundle -- you have to load the ESM version with relative imports** 3. and, separately the `init` function has been deprecated 2 is really the issue, and so I've had to go into the code to now load mermaid by ESM by default when the user is on mermaid > v10. I've tested this with: - CDN version < 10 (v9) - CDN version 10 - local path with version < 10 (v9) - local path with version 10 (new: also loaded as an ESM module) Separately, I chose to put all the mermaid stuff in one include because: - I think @pdmosses requested something like this - it's a bit confusing that some mermaid code is *not* in the include, and this makes modular components ... more modular - from a developer perspective, it's more clear what's happening with mermaid - mermaid is not render-blocking, so it shouldn't be in the `head` anyways --------- Co-authored-by: Peter Mosses <18308236+pdmosses@users.noreply.github.com>
