For backwards compatibility with existing users I default to yml and via the input I can now override it for our own repos that all use yaml.

Would be great if this can be released.

I'm happy to include this action input, but I think we should strict the input values to yml or yaml.

Thank you @marcofranssen, I appreciate the effort to contribute here. I've gone with a different approach and released it in v5.
