not sure why this was done the way it was considering that includes are
a feature the doc toolchain had previously. let's just always have some
kind of entry for the upcoming release in the dev manual builds even if
that means having a completely empty release notes chapter.
the release notes generation script isn't entirely functional right now
due to pre-commit hooks, but it's good enough for time being. we need a
better release process for notes anyway.

The big ones here are `trim-trailing-whitespace` and `end-of-file-fixer`
(which makes sure that every file ends with exactly one newline
character).
