Outputting to LaTeX coloring

[MilesCranmer]

x-ref MilesCranmer/AirspeedVelocity.jl#74

This is probably out-of-scope but I was wondering if there was any way to get a LaTeX-style coloring of text, for use in markdown-like contexts such as on GitHub? For example, $\color{red}\text{this text is shown in red.}$

This is mostly useful for GitHub actions that output GitHub comments – I'd like to control coloring of those via StyledStrings.jl.

IDK if this feature belongs in a stdlib but I definitely want it to exist somewhere.
