Make rewirting rebased commits imposible

[Rosuavio]

While it is possible to get tested commits on main, by opening a PR and when CI passes on the head of the PR pushing that commit to main, it is still possible to use a github merge method instead on the github web interface.

I dont like githubs merge methods. It would be really cool to make it impossible (or really difficult) use those merge methods.

It could help if I check CI status threw the gh cli tool instead of opening the web interface. (The less i look at github.com the less remember that the PR can be merged on the web.)
