I have been trying the JupyterLite integration for scikit-learn in scikit-learn/scikit-learn#25887.

As far as I can see, this is working fine, and it would be great to cut a new spinx-gallery release to have the fix from #1115 (The JupyterLite button links were always wrong with the scikit-learn gallery layout ...) and the feature from #1113 (ability to add cells to add warnings about JupyterLite and code to make the notebook work in JupyterLite).

Let me know if I can help in any way!
