Can you make it into a `prebuilt extension`? about jupyterlab_city-lights-theme

Hi,

Coming here from the issue on JupyterLab: jupyterlab/jupyterlab#11336

Although it's not decided if or when the managing of source extensions will be dropped, installing prebuilt extensions is still a nice improvement for the end users.

There is also a migration guide in the docs, and the python -m jupyterlab.upgrade_extension script should already help quite a bit with the migration: https://jupyterlab.readthedocs.io/en/stable/extension/extension_migration.html#jupyterlab-2-x-to-3-x

I once tried to support the prebuilt extension when JupyterLab 3.0 came out, and #100 is an attempt to prepare Python's venv setup prior to the actual implementation. As you can see in the PR, GitHub Actions somehow keeps failing in the topic branch whereas the equivalent test goes well on my local end. I gave up troubleshooting quite a while ago, but I try to make some time again to look into this.

I didn't know that jupyterlab/jupyterlab#11336 has been discussed. Thanks for letting me know!

For some applications, the only allowed way to install jupyter extensions is via 'pip' or 'conda' already. So the command jupytelab extension install does not work. One of the examples is the 'Jupyterlab Desktop'.

So hope this theme would be migrated to the prebuilt extensions successfully!
