jupyter-config/jupyter_notebook_config.d is not included in editable installs

[mpacer]

If you run pip install -e . it will not place jupyter-config/jupyter_notebook_config.d in any directory… furthermore it will overwrite any config that has been placed there.

For now, if you want to work on an editable install you still need to run

jupyter serverextension enable --sys-prefix jupyterlab_latex

Deploying data_files in an editable install isn't supported via setup.py develop or pip install -e or any known functional replacement from poetry, flit, etc. at this time. and is not specific to this package... jupyter-server/jupyter_server#351
