Add notion-mention roles #378
Description
Doing this nicely is blocked on ultimate-notion/ultimate-notion#166
- See https://developers.notion.com/reference/block#mention
- See https://ultimate-notion.com/latest/reference/ultimate_notion/#ultimate_notion.mention
- One role per mention type
- Start with an integration test for each mention type
- Make them work on the HTML builder, too - it should link to Notion
- Look at
.. notion-link-to-page::for inspiration (but that is a directive, not a role). - Document in README
- Use in sample
