Enable "Require branches to be up to date before merging"

[pponnuvel]

Sometimes commits can reintroduce pylint issues accidentially when it was already fixed in main.

Can we enable https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches#require-status-checks-before-merging

so that all PRs are up to date?

I think it's a good idea in general, not just for preventing pylint issues, to have this so that any PR passes all tests with the latest code.

To enable it:
[Settings]->Branches->main->"Require status checks to pass before merging" + "Require branches to be up to date before merging".
