Update from master as "Rebase" instead of "Merge"

[kurtextrem]

The feature request

Some repos are working with a "rebase"-only flow. "Update from master/main" currently only merges in.

I'd rather not introduce a new option in the menu in this case, but maybe rather make it configurable per repository what "Update from ..." does, so you can pick whether it starts a rebase or merges in.

Proposed solution

(again like for the other feature reqs: I can implement but would love your thoughts. I figure this one might be more controversial than the others. But I really love the 1-click solution with "Update from" instead of going through the "Rebase current branch" → select master flow.)

Looks good to me. You can go ahead with the implementation. :)

I agree that this should be a per-repository setting, probably in "Repository settings" -> "Git config" -> above the existing title "For this repository I wish to".
Additionally, since the "Git config" page is already quite tall, we should probably make it scrollable (see 3c79659 as a reference).
