Right now releaser-pleaser pushes the branch even if it is only for a "rebase", this wastes CI resources. Instead it should only push when there are changes to the files it owns.
Old: Push when there is a diff
origin/release-pr..release-pr
New: Push when the these two diffs are not the same:
origin/main..release-pr
$(git merge-base origin/main origin/release-pr)..release-pr
Closes #92
Right now the tests are still WIP. I was able to salvage the git test framework from a0a064d#diff-483ac1310305711011d4ac806cabfaacb53b40c182ddcd7f251b2cd141e3e229
