Upgrade Highlight.js

[dannyfreeman]

The version of highlight js this library depends on in sorely out of date and no longer supported:

An application I work on that uses shadow-cljs and nubank workspaces reports clashing versions of highlight that falls back to version 9.x.

This is even more relevant now in 2023
