chore: add additional structure to generated docs (#3985)

* For API docs, wrap each generated document in `.docs-api`
* For markdown docs, wrap each generated document in `.docs-markdown`
* Remove the `h1` from API docs that contained only the component name
* Change the `h2` for API docs to be a friendlier title followed by an example import.
* Increase header level for API by one across the board (so that they're "under" the new `h2`)
* A few misc. docs fixes
