Automatic dependency update workflow fails

[kaklakariada]

When PK updates workflow files during a dependency update, pushing the changes fails because workflows permissions are missing for the workflow. See also https://github.com/exasol/google-cloud-storage-document-files-virtual-schema/actions/runs/9311902315/job/25631964808

 ! [remote rejected] dependency-update/20240531022012 -> dependency-update/20240531022012 (refusing to allow a GitHub App to create or update workflow `.github/workflows/broken_links_checker.yml` without `workflows` permission)
error: failed to push some refs to 'https://github.com/exasol/google-cloud-storage-document-files-virtual-schema'
Error: Process completed with exit code 1.

The workflow dependencies_update.yml runs PK fix which potentially updates workflows.
Due to restrictions of GitHub permissions it is not possible for a workflow triggered by an event to modify GitHub workflows (see https://github.com/orgs/community/discussions/35410). That's why pushing the changes failed. A workaround would be to use a separate PAT, but this is too much effort.

We decided to skip running PK fix. The user must checkout the branch locally and run PK fix manually.
