Introduce "Contributors" group for frequent contributors

Introduce "Contributors" group for frequent contributors so that we can assign the users/group to issues.

This should be documented in the repo when people are being considered to be added and what it means to become one.

Hi @tomkerkhove How do one become a member of keda, what's the requirements to become a member?

We did not formally close this so no requirements for now

Maybe it's a good moment for working on this? 🤔

I think that this issue can cover better the case. If you agree, we can close this one
