text: Title: Duplicated CI executions in GH Actions
  Body: Just noticed that we got duplicated test executions (for pull_request and push).  Something might be changed from the GH Actions side and that could be a really quick adjustment. So it's not a bug, but a feature that we want to disable.

  Good first issue, help wanted from anyone willing to contribute.
