Support for colon fences

[rowanc1]

Context

A lot of the existing jupyter book content has these, and is not rendered using mystjs.

Proposal

Looking forward to knowing more about where in the current tools we can implement this. I think it might be in the docutils library?

Tasks and updates

Cool! Is the idea to remove the same plugin from https://github.com/executablebooks/markdown-it-myst-extras?

Oh man, wish that either @chrisjsewell or I had caught that in the review. Wasn't aware that this was already ported. Thanks for pointing it out.

I think the best thing to do is take it out of docutils, release a new version, and rearrange the import in mystjs.

Ok, this cleans that up:

• 🐛 Use colonFence from myst-extras executablebooks/markdown-it-docutils#41

Ok, this is all fixed up in #56 and confirmed that it is working! :)

Thanks @agoose77 for the catch here.
