Bro/Zeek Script Support in Highlight.js

Hello all!

I've put together a language file for the popular Highlight.js library for the Bro/Zeek script language. Highlight.js is the syntax highlighting library Discord and Slack use and is useful for websites that include automatic client-side syntax highlighting.

Let me know if you have any comments or suggestions! If you don't, a thumbs-up on the pull request would be appreciated to gauge how much people want this feature in Highlight.js.

Thanks!

Nice! Thanks! I love as all of these highlighter supports show up because it means that the language keeps being highlighted correctly on all of these services.
