NBgrader does not install under Jupyterlab 4.3.0+

[perllaghu]

Tested on linux [linux mint, 22 (Wilma); based on Ubuntu-noble]

Testing process was:

rm -rf venv
virtualenv venv --python=/path/to/python/version/3.11.7/bin/python
source venv/bin/activate
pip install jupyterlab==4.3.4 nbgrader==0.9.4
jupyter labextension list
deactivate

I tested a variety of jupyterlab versions.... assume each one is wrapped in a remove venv to deactivate cycle,
