Upgrade and fix ipywidgets

[jdemeyer]

There are various issues with widgetsnbextension:

1. It must be installed using pip. The typical python setup.py install does not work. See python setup.py install command should error out and ask user to use pip jupyter-widgets/ipywidgets#718. This is fixed by Use pip to install Python dependencies #20218.

2. We need to enable the widgetsnbextension for ipywidgets to actually work.

3. We add a patch to remove deprecated @interact abbreviations. This patch is applied upstream to version 6. To be more compatible with SageNB, we add this patch right now.
