Example Jupyterlite notebook in docs doesn't connect to a kernal

[dwootton]

Description

The example notebook embedded in "configuration" in the docs doesn't work for me.

Reproduce

Go to configuration page: https://jupyterlite-sphinx.readthedocs.io/en/latest/configuration.html
Try to use the jupyterlite notebook.
For me it says kernal unknown

Expected behavior

I would expect it to work
