The description of KaTeX formula implementation could be improved

[DavidEHufnagel]

On collections/_components/math/index.md currently it says that formulas must be enclosed in "$$..$$". What this misses is the requirement for brackets. I recommend it suggests enclosing a formula in "$${..}$$" to make that requirement clear.

Thanks for submitting a suggestion. However, I wasn't aware of a requirement for enclosing formulas in brackets when using KaTeX. Where is it stated?

In any case, our current KaTeX tests appear to render properly on GitHub Pages, and none of the source formulas are enclosed in $${..}$$.
