feat: use \autoref in latex

[domoritz]

\autoref automatically adds the prefix and also makes the whole reference ("Figure 3" instead of just "3") clickable.

This looks promising. We probably also want to add \def\sectionautorefname{\S} to generated documents preserve how we refer to sections. We also need to ensure that the hyperref package is being used.

I think it's actually better to let each template decide how they want to render sections.

All templates in this repo import it. Is there another way to ensure that a package is there?

Fwiw, I'm using

\makeatletter
\renewcommand{\sectionautorefname}{\S\@gobble}
\makeatother

(which I got from Stack Overflow). The gobble is necessary because autoref adds a space after the ref name and we don't want it
