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

+| otp-version        | The Erlang version, e.g. `OTP-26.0`

+| gleam-version      | The Gleam version, e.g. `v0.23.0`
+| rebar3-version     | The `rebar3` version, e.g. `3.18.0`

+
+accessible as `${{steps.<setup-beam-step-id>.outputs.<Output>}}`,
+e.g. `${{steps.setup-beam.outputs.erlang-version}}`
+
+### Version file
+
+A version file is specified via input `version-file` (e.g.`.tool-versions`). This
+allows not having to use YML input for versions, though the action does check (and
+will exit with error) if both inputs are set.
+
+**Note**: if you're using a version file, option `version-type` is checked to be `strict`,
+and will make the action exit with error otherwise.
+
+The following version file formats are supported:
+
+- `.tool-versions`, as specified by [asdf: Configuration](https://asdf-vm.com/manage/configuration.html)
+
+Supported version elements are the same as the ones defined for the YML portion of the action,
+with the following correspondence.
+
+#### `.tool-versions` format
