mentioning `sphinx.ext.mathjax` might be unnecessary?

[mmesiti]

I am trying now with relatively complicated latex expressions and they all seem to be rendered using mathjax even if mathjax is not mentioned among the extensions.

• the HTML generated is exactly the same
• as a crosscheck: I do get the 'updating environment' message with 'extensions changed' when I add or remove sphinx.ext.mathjax

Perhaps loading the extension explicitly is not necessary any more?

I also think it's not needed.

Here I was teaching Sphinx and we tried LaTeX in it and we didn't need the extension: https://coderefinery.github.io/reproducible-python-ml/documentation/
