Use custom build of the highlight.js to reduce its bundle size

According to https://twitter.com/samccone/status/837173944293568512 providing only needed languages to highlight.js can reduce its bundle size significantly. Seems like a low hanging fruit to optimize since SG should only support JS/JSX.

We don’t have highlight.js in the bundle, it’s all server side ;-)

And actually it should support any language you define for fenced code block. At least HTML, for example.

Server-side? Can you elaborate please?

We send HTML from webpack loader, so we don’t have highlight.js on the frontend.
