[Feature] Add support for equation numbering

[SteelWagstaff]

MathJax allows users to include automatic numbering for equations. See https://docs.mathjax.org/en/v2.7-latest/tex.html#automatic-equation-numbering + http://docs.mathjax.org/en/latest/input/tex/eqnumbers.html. We do not support this feature in Pressbooks currently. Turning it on in webbooks seems fairly straightforward, but we will want to ensure this works properly in ebook and PDF exports. #23 is related

Yes, we're hoping that this can be implemented across the board soon. This is proving to be an important feature in many STEM texts we are supporting. They rely on MathJax to render accessible formulae and need to reference equations at different points throughout the texts — numbering/indexing/labelling is a surefire way to point to equations across all the formats (rather than asking users to look at the equations 'above' or 'below' another element in the book). It'll make for a much easier workflow and aesthetic, accessible book!

Hey team - just checking in on whether this issue is being addressed in any current sprints/planned for the near future?
