Update highlight.js library to 10.7.1+ bringing HLSL support to Game developers everywhere

Hello,

I am a graphics software engineer and use Discord daily for solving problems and sharing code snippets with other developers in professional and educational settings.

While Discord's syntax highlighting is very helpful in this regard, it is lagging behind on highlight.js library's advancements. Many improvements, bugfixes and support for a number of new language grammars have been added to highlight.js in the past year, one of the most important to the game developer industry being HLSL High-level shader language (HLSL.) it is currently the most ubiquitous language that shader code is authored in, in large part by its use in the Unity and Unreal real-time engines.

HLSL support in particular was added in version 10.7.0, with 10.7.1 being the last version before possible breaking changes arrived in 11.0.0

https://github.com/highlightjs/highlight.js/blob/2dd87a6ef58c8c886dd209076aa6661ffae89577/CHANGES.md

Updating highlight.js to at least 10.7.1 has a low effort and low risk factor but would benefit so many that work on videogames and interactive media, using Discord to communicate everyday. 

Thank you!
