Docs TODO list

[mathisonian]

All of these would be very nice to have:

• [ ] generate component documentation directly from the idyll-components module
• [ ] figure out a story for versioning the documentation
• [ ] basic blog post template for announcements, etc.
• [ ] move this repo back to idyll-lang/idyll
• [ ] add more examples to gallery
• [ ] iframe in examples in gallery so we can overlay links to the source, etc.
• [ ] syntax highlighting
