feat: add ability to run commitlint on events that are not pull requests

For any event that is not of type `pull_request`, we consider there will be a `GITHBU_SHA` defined and run lint against only this specific commit
sha.
This supports not only events of type `pull` but also other events that provide us a `GITHBU_SHA`, like `check_suite`.
