Depend on jupyterlite-core

[jtpio]

Similar to jupyterlite/xeus-python-kernel#114

The core functionality of the jupyterlite package is being extracted to a new jupyterlite-core package in jupyterlite/jupyterlite#994.

This will allow site deployers to make slimmer deployments without having to bring the Pyodide kernel by default.

TODO

• Try depending on jupyterlite-core built from Add the jupyterlite-core Python package jupyterlite#994
• Update to the real jupyterlite-core dependency when a release is available (likely after Add the jupyterlite-core Python package jupyterlite#994 is merged)
• Update the docs environment
• Re-add a Python kernel to the docs environment

[jtpio]

Docs seem to be building fine:

We can add the Pyodide as federated_extension to get the previous behavior of having the Pyodide kernel available by default on the docs. We could also choose Xeus Python.

Looking good now after updating to jupyterlite-core>=0.1.0b19: https://github.com/jupyterlite/jupyterlite/releases/tag/v0.1.0b19
