TypeScript is a widely used programming language, but Stash doesn't support TypeScript highlighting. Stash uses highlight.js for highlighting. I implemented TypeScript highlighting for it which is available in highlight.js 8.1, but apparently Stash has not updated to it yet.

Nowadays Stash uses highlight.js 7.3, which does not have Gherkin support.
It was going to be awesome if we could update it to at least version 8.1 which has such support
