Deprecation warning for Jupyter in mkdocs

[rogerkuou]

warning when executing

mkdocs serve

INFO    -  DeprecationWarning: Jupyter is migrating its paths to use standard platformdirs
           given by the platformdirs library.  To remove this warning and
           see the appropriate new directories, set the environment variable
           `JUPYTER_PLATFORM_DIRS=1` and then run `jupyter --paths`.
           The use of platformdirs will be the default in `jupyter_core` v6

As discussed, suppressing this warning can easily be done by setting an environment variable before running mkdocs, e.g.: JUPYTER_PLATFORM_DIRS=1 mkdocs serve

However, I was not able to find a way to set this environment variable as the project was being installed, either in pyproject.toml or mkdocs.yml

Because this is just a warning on the server, we can ignore it.

However, I will resolve the CODE_OF_CONDUCT.md warning also given when calling mkdocs serve.
