A couple of CI improvements for the Community add-ons.
Docker build cache restored from GitHub, no longer takes the ref into account, this allows re-use of the cache in more cases. Lets Docker figures it out (which is what our Dockerfiles are optimized for).
Applied the same to the deploy, allowing the deploy to use the same cache from the CI.
Prevents GitHub cache artifacts to grow forever. This is a known issue, however, this PR applies a workaround.
Fix applied to the label checker, to ensure it works for forked repositories as well.
