GH Actions has no permissions to use rebase command, says Dependabot

[joriswitteman]

I can't get Dependabot to accept rebase commands from the gh-actions bot:

Sorry, only users with push access can use that command.

If I follow up with a personal rebase comment manually, Dependabot accepts.

My workflow file:
