Add action types with validation

[krzema12]

This PR adds typings for this action, using https://github.com/typesafegithub/github-actions-typing. Thanks to this, one can consume this action in a type-safe way using https://github.com/typesafegithub/github-workflows-kt.

Hey @krzema12, thanks for your contribution, I was not aware of that. Looks cool, can you share how this is used?

[krzema12]

Sure! The only use of this I'm aware of is by https://github.com/typesafegithub/github-workflows-kt. More precisely, there's a Maven-compatible server that vends the Kotlin bindings for the actions on demand. It generates Kotlin code and compiles it on the fly, using the typings to know what Kotlin types should be used by the binding. You can read more about this project here: https://www.javaadvent.com/2024/12/the-journey-of-providing-kotlin-bindings-for-github-actions.html

I'm about to use your action here: typesafegithub/github-workflows-kt#1758

There's one more thing left to do: can I ask you to release a new version of this action? Only then the typings will be usable by the mechanism described above.

Thanks for sharing. This looks awesome.

I've seen you already use v0.11.0 which I released tonight. Let me know if anything needs to be fixed.

All is fine, thanks!
