Support range select for amending commit attributes
Is your feature request related to a problem? Please describe. Currently when you press 'a' on a commit, you see a menu with options to reset the commit author, amend the commit author, and add a co-author in the commit message.
But this only works for individual commits. If you want to add a co-author for a range of commits, you'll need to perform the action on the commits one-by-one.
Describe the solution you'd like Support these three actions for a range of commits.
Additional context For reference, here's the PR which added the ability to add a co-author to an individual commit https://github.com/jesseduffield/lazygit/pull/2912
I don't believe we yet have a way of saying that you want to perform a specific action on a range of commits as part of a rebase, so we that may need to be added as part of this work.
I'd like to work on this, if possible :)
