Description

For nightly builds, we want to select the release branches dynamically (rather than using the automatic selection through GHA schedule). We want to do this dynamically because the GHA feature for branch selection seems to be kind of limited right now, e.g.:

• Don't run a branch that hasn't have any changes in the past 1 day (or any other time period)
• Run only the most-recent release branches and ignore older release branches (similar to what we're doing in flink-ci/git-repo-sync:sync_repo.sh right now)

A custom action that selects the branch and commit hash enables us to overwrite this setting.
