Update base notebook packages

- We should stop auto updating 3.6 now, so we can move on to
  newer notebook packages - a new notebook version ought to fix
  issues like 2i2c-org/infrastructure#1170
  for example.
- No longer explicitly pin nbconvert, as whatever version notebook
  brings in should be sufficient.
- Bump up ipywidgets and jupyterlab while we're at it.
- No longer pin jupyterhub-singleuser either, as that too works
  properly with 3.7
