With a small remark regarding logging

[987Nabil]

@mzuehlke I tried to put this changes on a branch in my fork and let this run. I put some settings into a file referenced via --repo-config, but even when defining a hook without a group/artifact id, the hook does not run. Do you have an idea why? Because I don't 🤷

[987Nabil]

Ok, I guess I found it. The monoid def of RepoConfig was missing a combine of the hooks
