Better support for the remark-gfm plugin

Summary

If you enable the remark-gfm plugin via the remark option in the greenwood.config.js, it mostly works, but footnotes do not work.

Details

remark-gfm is one of the few ways that I can find in the unifiedjs ecosystem for handling footnotes in markdown. The alternative, remark-footnote, has a note on it saying that it is deprecated and to use remark-gfm. I'm still exploring alternatives, but better support for this fairly standard remark plugin would be great.

Thanks for the report, I had tried playing around with this myself during our chat but didn't see anything obvious as to why just that specific feature wouldn't work, but could be attributed to maybe some of our unified and related deps being out of date?

Let me explore this as part of #1247 and see if anything materializes after doing a bunch of version bumps.
