Format and lint ipynb files with black

[phoevos]

Currently, the ipynb files provided as part of the notebooks directory are skipped when running black to format or lint the project source:

Skipping .ipynb files as Jupyter dependencies are not installed.
You can fix this by running ``pip install "black[jupyter]"``

Goal

Investigate the option suggested by the black output above and make sure that black runs properly for Jupyter notebooks.
