forgejo/web_src/js/features/highlight.js
silverwind b9690d7c0b move highlight.js to npm/webpack (#10011)
- introduced window.config to help with js-based lazy-loading
- adjusted webpack chunk naming to avoid 'vendors~name.js' that webpack
  defaults to for vendor chunks.
- added theme class to html and prefixed all selectors. this is
  neccesary so that the theme styles win over the lazy-loaded ones.
