Tests whether commits can be cherry-picked into a target branch. Originally this is for checking of commits from a pull request can be "merged" into other branches than their destination branch, e.g. release branches.

The action fails if any of the used commands fail and the pseudo-code is something along the following lines:

git clone --branch $TARGET_BRANCH https://github.com/$TARGET_REMOTE.git
git cherry-pick $SOURCE_COMMITS
