[WIP] Allow custom subpath for docs within the "docs" folder

e.g.,

The default is

`docs/*.md`

This allows

`docs/somedir/*.md`

or

`docs/somedir/anotherdir/*.md`

Notes:

- All URLs are still /docs/*.html (i.e. the subpath does not get preserved in the link).
- Files in `translated_docs`, if any, will still only be one level
- This should not affect translations or versioning
