The workflow that updates `actions.yml` and `approved_patterns.yml` after merging dependabot PRs is broken

The workflow that updates actions.yml and approved_patterns.yml after merging dependabot PRs seems to be broken after this change.

Example:

[main 67e662b] Update actions.yml and approved_patterns.yml based on .github/workflows/dummy.yml
 2 files changed, 24 insertions(+)
remote: error: GH006: Protected branch update failed for refs/heads/main.        
remote: 
remote: - Changes must be made through a pull request.        
To https://github.com/apache/infrastructure-actions
 ! [remote rejected] main -> main (protected branch hook declined)

we have fixed this temporarily by disabling branch protection again, tracking re-enabling it in #693
