Consider changing or removing Author field from PyPI

[ryanlovett]

Proposed change

The Author field on the left side of https://pypi.org/project/jupyter-server-proxy lists a specific person (me), but this project has been managed by a group of people for a while now. I suggest that we set it to be something broad like Jupyter Development Team (jupyterhub, jupyterlab, and notebook do this). Alternatives are to remove the Author field or expand it to include frequent contributors.
