Add option to show commit AuthorDate instead of CommitDate

Basically https://stackoverflow.com/questions/71461868/how-to-view-author-date-on-github-com

On Github's web UI, add an option to show AuthorDate. This doesn't match what git log shows and is relevant usually for rebases.

[toschlog]

Yes, please. We need a Settings option to select between Author Date and Commit Date on https://github.com/organization/repository/commits/branch.
