See #1026 (comment)

The rationale by GitHub is to avoid perpetually running loops, if I understand correctly.

Solutions:

• replace the auto-commit thingy by a non-committing step which will trigger blocking errors requesting the PR author to run that locally & commit (this is very classically used)
• or reconfigure the linter to ensure the token used is able to trigger workflows, which is not the case

The work-around I found for now is (as I did on #1026) to push an empty commit (e.g. git commit -m "Run workflows" --allow-empty).
