create JupyterHealth team

[minrk]

implementation of #752 which has more details on the proposal. Feel free to ask questions here or there if there are any questions or concerns with (or especially objections to!) the proposal.

If this is merged, I'll go ahead and add jupyterhealth to the Jupyter GitHub Enterprise and consider the process complete

Any more tasks to take?

Thanks for the approvals!

Following our consensus-seeking approach, I'll merge this with existing approvals after 2 weeks (February 4) unless anyone asks for changes or more time. I'd particularly like review from folks who asked questions in #752 (@choldgraf @manics) to make sure those questions really are addressed. I didn't put the check-in after a year suggestion in the docs, because I figure it can be more of an Issue than documentation.

I can do calendar math, I promise. I meant February 4, not January 28.
