I can't merge a critical backport

[roberth]

Describe the bug

I can't merge a critical backport because CI doesn't run.
I have push permission, but I am not an admin.

This happened while attempting to fix the release.
I was not able to trigger the Hydra job because of this, delaying the hotfix.

The backport:

• [Backport 2.13-maintenance] Revert #6204 to fix regression, add nixpkgs/lib/tests as regression test #7622

Steps To Reproduce

1. Make a backport using the label
2. There's nothing I can click. PR state from my viewpoint is:
   
3. My attempt to trigger the CI failed

error: failed to push some refs to 'https://github.com/NixOS/nix.git'

Expected behavior

install_test triggers, runs, completes, and I can merge it.

nix-env --version output

@domenkozar Do you have an idea why installer_test might not report a status?

[zowoq]

A github action can't start another action unless it uses the non-default token.

Closing and reopening the PR is the simplest workaround.

If all of the checks need to run clean, you may be able to goose it by getting cachix set up for the installer tests. Edit: sorry. Wasn't thinking. This would just be for your fork. Doubt this matters for merge.

Edit: though I feel like the expected status has something to do w/ perms

Yes, that's an issue with the backport bot (don't have a pointer handy, but it's a known issue, and not trivial to fix IIRC, something like what @zowoq mentions).

It's strange that the backport branch is protected though, I think I unstuck this a couple time by force-pushing to it 🤔

I've removed the requirement for the installer test to pass on maintenance branches.
