Add a 'desktop-test' hub

This puts people directly into
https://github.com/yuvipanda/jupyter-desktop,
with an XFCE environment. There's no specific use case
for this yet, but I'm sure we'll find one soon enough!

This has the same home directories as datahub.

No HTTPS yet, because of jupyterhub/zero-to-jupyterhub-k8s#1448
