Update dependancy to MathJax 3

[ElieGouzien]

MathJax 3 is bringing substantial improvement, in particular new extensions that allow using nice LaTeX packages.

It would be nice to update this package to support MathJax 3.

The mathjax-node package was a hack to allow MathJax v2 to be used in node applications (since v2 was only meant for in-browser use).

MathJax v3 was designed around allowing use in node applications without the need for a wrapper like mathjax-node. So you can use MathJax v3 directly. See the MathJax node demos repository for examples.

The README file here should be updated to point to that repository.

Hey, thanks for your answer, that's very instructive.

Beyond writing in the doc that mathjax-node is not needed anymore, I still think that having a mathjax-node version using mathjax 3 would help all the projects that uses mathjax-node to update to mathjax 3 without having to get to know the internals of mathjax , and without significant change to their code.
