.github: sync_ci.yml: Add workflow to syncronize workflows

Adds a sync_ci.yml that syncronizes the ci files to other branches.
Is added only to .github/workflows/cron.yml and not to
.github/workflows.mirror/cron.yml because it is assumed that the
branches pushed the ci to are mirror under the mirror repository,
not requiring to patch the ci again, instead, just mirror using the
mirror.yml like the main branch.
