Don't escape square brackets in math expressions
The upgrade to [pulldown-cmark](https://crates.io/crates/pulldown-cmark) 0.11 (see Backwards-incompatible Changes) includes official support for LaTeX-style math expressions.
With the markdown parser supporting this syntax natively, math expressions are now processed correctly without edge-cases.

This sentence uses `$` delimiters to show math inline: $\sqrt{3x-1}+(1+x)^2$
This is the same math expression expressed as a block element:
