⚙️ Gizmos: Support ActionText

- #709
- #2200 (review)

Markdown is cool, but it's nerd-forward.

ActionText is a much more human-friendly way of implementing rich text
in Rails applications.

I don't know enough about [Trix] to know if it will work in multi-user
contexts; or how it will work with rich-embeds, ala Notion or Google Docs

But I think it's a good-enough-default for now; and if we get to the point
where embeddables or multi-user editing of a field is important we can
figure that out.
