GH release tools

[jarrodmillman]

A release looks something like this:

$ changelist ${ORG}/${REPO} v${PREVIOUS} main --version ${VERSION} >> ${VERSION}.md
$ # Add ${VERSION}.md to CHANGELOG.md
$ # Update `version` in `pyproject.toml`
$ git add pyproject.toml CHANGELOG.md
$ git commit -m "Designate ${VERSION} release"
$ git tag -s v${VERSION} -m "signed ${VERSION} tag"
$ git push --tags origin main
$ # Make a github release from the tag

The first two manual steps are project specific and can be easily scripted there or handled manually.

However, it would be nice to help automate the last manual step so I could use changelist to create a GitHub release for the tagged release with ${VERSION}.md as the body or note and v${VERSION} as the title (with the option for it to be a pre-release).
