Add known branch exceptions to version matching (#242)

* Do a bit of YAMLlint'ing

* Ease consumer cache invalidation

By providing an output with the action version we ease
cache invalidation on consumer, due to the fact we can
now stop worrying about changes to the action's cache itself

Might also be interesting for self-hosted runners...

* Remove duplicates

* Do further validations for robustness
