Figure out how to automatically include generated REST API documentation in the doc site

Suggested by @ialarmedalien , and a very good idea:

export and save the API docs that huma produces and add them to the DTS docs (ideally using the magic of github actions, rather than having to do it manually)

The short story on this issue seems to be that persistent generated API documentation seems not to be "a thing." There are various providers of generated API documentation, and they all seem to want everyone to flock to their platforms to get hosted documentation. I wonder if it's sufficient (once we have a "permanently hosted" DTS instance) to just link to the online docs, since they're already formatted properly.
