Update highlightjs to 8.2 version for GitLab 7.3

Here is the commit bump https://github.com/isagalaev/highlight.js/commit/fbeaf909be18159d12881602dbf584857b04a609

Here are the changes for highlights:

Version 8.2

We've finally got real tests and continuous testing on Travis thanks to Jeremy Hull and Chris Eidhof. The tests designed to cover everything: language detection, correct parsing of individual language features and various special cases. This is a very important change that gives us confidence in extending language definitions and refactoring library core.

We're going to redesign the old demo/test suite into an interactive demo web app. If you're confident front-end developer or designer and want to help us with it, drop a comment into the issue on GitHub.

As usually there's a handful of new languages in this release:

• Groovy by Guillaume Laforge
• Dart by Maxim Dikun
• Dust by Michael Allen
• Scheme by JP Verkamp
• G-Code by Adam Joseph Cook
• Q from Kx Systems by Sergey Vidyuk

Other improvements:

• Erik Osheim heavily reworked Scala definitions making it richer.
• Lucas Mazza fixed Ruby hashes highlighting
• Lisp variants (Lisp, Clojure and Scheme) are unified in regard to naming the first symbol in parentheses: it's "keyword" in general case and also "built_in" for built-in functions in Clojure and Scheme.
