docs: add rehype-gfm-components plugin

[claylo]

Write GFM, view it on GitHub, deploy it with Starlight. The same Markdown file for both -- all content easily viewable on GitHub, still transforms to rich and interactive components on your Starlight site. No MDX, no imports.

Description

Just a plugin for those who want to use Starlight ... and also want their docs to be fully readable on GitHub. (It can't be just me, right?)

Thank you for all your efforts on Starlight! I'm loving it.

Thanks for the PR and plugin @claylo!

One note: looks like this provides a Starlight plugin, so I think it would make sense to move this up to the “Community plugins” section (rather than the tools and integrations section where it is now).

Also, if you’ll permit me a pinch of feedback, it looks like there’s something up with the file tree in your example site? Maybe some styles that aren’t quite right? And the .astro icons are missing.
