Removes backport and release-notes scripts

* Also deletes the unnecessary @osd/release-notes package.
* Backport is unnecessary since we're adding a backport action in #1233.
* Release notes are generated with `git-release-notes`, and there's no
need to maintain a package dedicated to release notes for now. Future
work can be done to integrate existing release notes repositories
instead of reinventing the wheel.
