Here's jupyter_server, a new port in the jupyter stack needed for 
jupyterlab and a few other things.

The attachment contains a few things:
- py-nodeenv, a new port needed by pre-commit (jupyter_server fails at 
  build time without pre-commit having all the ports it needs)
- a replacement Makefile for pre-commit adding the new RDEP and bumping
  the port.
- 2 new TDEPs for jupyter_server
- The new jupyter_server port itself.

Note that jupyter_server cannot go to the 2.x series until 
jupyter-notebook supports the newer version. I added a comment about that 
in the Makefile.

ok on importing all these new ports?
