CI is failing

This also fails if I do tox -p

For some reason PYC files are getting generated in the demo_configuration folder. One of the `tox -p` actions is generating this because if I do `rm -r src/deploy_tools/demo_configuration/__pycache__/` and `pytest tests` it works, but `tox -p` always fails as the __pycache__ folder gets re-created.

```

/home/runner/work/deploy-tools/deploy-tools/src/deploy_tools/demo_configuration/__pycache__/make-beamlines.cpython-312.pyc
