@jtpio this is gonna break because there is no binary for y-py supporting 3.11

Isn't it already breaking regardless of whether 3.11 is tested on CI?

The 3.11 install checks are passing though: https://github.com/jupyter/notebook/actions/runs/3335770429/jobs/5520203591

no binary for y-py supporting 3.11

This is tracked in y-crdt/ypy#82

CI is passing. Hopefully we can rely on GitHub Actions being able to build from source while waiting for y-crdt/ypy#82.

Opened #6622 as a follow-up (noticed while doing this update).
