02 Maintain: Update Workflow Files

There is a build error that needs to be fixed: https://github.com/carpentries-incubator/machine-learning-neural-python/actions/runs/17568692204/job/49900494337

```
Pushing pull request branch to 'origin/update/workflows'
/usr/bin/git push --force-with-lease origin HEAD:refs/heads/update/workflows
remote: Permission to carpentries-incubator/machine-learning-neural-python.git denied to carpentries-bot.
fatal: unable to access 'https://github.com/carpentries-incubator/machine-learning-neural-python/': The requested URL returned error: 403
Error: The process '/usr/bin/git' failed with exit code 128
```

Start with the failed GitHub Actions run linked in the issue and inspect the repository's workflow files referenced by the “02 Maintain” task. Trace the push to the update/workflows branch and determine why carpentries-bot receives a 403. Done means the workflow completes without the permission error.
