Explore JupyterLite-Sphinx for interactive examples in docs

[rmorshea]

Current Situation

Right now we render interactive examples from the docs, but there's no way to edit the source to see the output change. This is because the examples are all running server-side and we can't allow readers to run arbitrary code on the server.

Proposed Actions

Explore jupyterlite-sphinx as a way to run interactive examples client-side.
