Add support for RISE slides in JupyterLab

[fcollonval]

This PR:

• adds support for jupyterlab-rise
• clean some commented code
• fix setting metadata when modified for JupyterLab 4+

FYI @parmentelat in JupyterLab 4, metadata obtained are a copy of the document metadata. So modifying them required to explicitly call setMetadata with the new value.

Thank you @fcollonval , this looks great! I plan to give a try to this in the coming days (or next week-end), is that fine with you? Also, are you able to build the package locally? (I am afraid that I am not anymore... I've been using rc releases on pypi, but it would make testing easier if I could recover local builds :) )

thanks @fcollonval for pointing this out, I'll keep it in mind :)

I succeed to build the wheel with BUILD_JUPYTERLAB_EXTENSION=1 python setup.py bdist_wheel executed in the root folder with nodejs 18 and

As the workflow build does create the sdist and wheel on the CI, I can push a commit uploading those artifacts as job artifacts. So it will be easier to test them locally by downloading the package from GitHub.

Hey @fcollonval , I have been able to test this, seems to work great! I will package a new release right now.

I had not used RISE for a long time, so it took me some research to find out how to run a quick test. Maybe I would have two quick suggestions for the other potential users of RISE:

1. What got me started was the example notebook on binder at https://github.com/jupyterlab-contrib/rise, it's a great example so maybe I would suggest to mention it explicitly in the documentation? And then it could help to document how to create a new slide etc with the new jupyterlab extension.
2. In the RISE documentation at https://rise.readthedocs.io/en/stable/usage.html#jupyterlab indicates that JupyterLab is not yet supported, I guess this can now be revisited!
