fix: Force push git changelogs

[SuperQ]

We need to use force push to update skipping the default branch protection rules.

Seems like branch protection won't allow pushing at all, even when using --force.

INPUT_PUSH_OPTIONS: --force
remote: error: GH006: Protected branch update failed for refs/heads/main.        
remote: error: Changes must be made through a pull request.        
To https://github.com/prometheus-community/ansible
 ! [remote rejected] HEAD -> main (protected branch hook declined)
error: failed to push some refs to 'https://github.com/prometheus-community/ansible'

Force pushes to protected branches has to be enabled in the repo settings for that to work.
It's actually in the docs for the action: https://github.com/stefanzweifel/git-auto-commit-action#push-to-protected-branches

@SuperQ could you enable this setting in branch protection? I don't have access :(

How I did it was to add prombot as a "allowed to force push" exception.
