Description

MathJax is 3.2.2, but its configuration is for 2.7.7

Reproduce

1. Install a clean minimal Debian/unstable
2. $ sudo apt-get install python3 pip
3. $ pip install notebook
4. $ jupyter notebook

At https://github.com/jupyter/notebook/blob/main/notebook/app.py#L91 the version is 2.7.7

In js console the version is 3.2.2.

Major version mismatch causes AMS configuration for MathJax to fail.

Expected behavior

Context
