Are these notebook tests needed anymore? The CI seems to just run dev_tools/execute-notebooks.py which collects and runs all notebooks.

Qualtran/.github/workflows/ci.yaml

Lines 53 to 67 in a49d0e0

This is what I got from @mpharrigan:

there should be a pytest for each notebook marked with that mark so local users can easily check the notebooks alongside their unit tests and isolate failures

The notebook tests are skipped for pytest during the CI (tested via execute_notebook) but will run locally (if you forget to -m "not notebook")
