Mathjax v3.2.0 was released on 2021-06-17, see https://github.com/mathjax/MathJax.

This will be done in three steps:

• Step 1: Fix Sage to be compatible with MathJax3. Done in Make Sage output MathJax3 compatible htmls #31517.
• Step 2: Provide mathjax spkg upgraded to MathJax3.
• Step 3: Configure Sage to use MathJax3.

This ticket focuses on the Steps 2 and 3.

To install mathjax, you can download the tarball from a temporary URL:

https://drive.google.com/file/d/1-tMjjIwftzoGngFh549_kUO3Chmy3qhI/view?usp=sharing

and place the tarball in upstream/ and make, or you can just do make since the tarball will be automatically downloaded from the attachment of this ticket after unsuccessful attempts to download from sage mirrors.

We can now choose whether to use mathjax CDN or not. The default is not to. To use CDN, do

export SAGE_DOCBUILD_OPTS="--use-cdns"

before make online doc.
