better bot branch filtering

[schacon]

We're really just looking for "dependabot". It would be nice to allow users to add bots to the "bot" list used for filtering branches (and definitely add github-actions[bot] to the list). Maybe both better defaults and also a config file with regex patterns or something.

Thank you for opening this issue on behalf of my Discord Request.

I think it's important to have both options customizable, for instance, we have a automation that utilises our automation account https://github.com/EventivaLtd - but this user probably won't ever commit to anything which isn't our organization, and therefore isn't relevant so you wouldn't want it on a central list.

GitHub actions should be ignored for sure. I don't think I currently work on a single project which doesn't have some level of CI / CD actioned by the GitHub actions user.

Adding to this, I think it needs to be something which is commited into the repo level as well as managed on the individual profile. If I am using GitButler in my organisation, I want all my colleagues to be able to open the same repo in GitButler and it to work exactly the same out of the box. #2932
