Fix input name in action.yml

[browniebroke]

There is a Github annotation when running this workflow as documented in the README, telling that the inputs are invalid. You can see it in your own Actions tab.

The action actually uses input_config internally which -I think- is to be declared as config in the action.yml file.

This should fix this annotation.

Thank you! 🐛 🎉

I still don't understand why I had it like that... and even more, how did it even work "correctly" at some point 🤔 🤷‍♂️ 😅
