Currently we run the release jobs for all PRs, this leads to red CI runs
any time we have unreleased changes in one crate used by another i.e.,
basically days after a release comes out.
Add a `release.sh` script that has more smarts to try and figure out if
the patch series currently ontop of tip of mater contains changes that
imply its a release PR. To do so we check for changes to the version
field in the manifest of each crate.
