I opened a PR to add Gleam to the list of Highlight.js grammars: highlightjs/highlight.js#4049.

It was requested that the dist/ directory be included, as outlined in the "Create your repository" section of the third-party docs.

Generating the dist/ directory is outlined in the "Packaging" section.

Note that this is only needed prior to v12 of Highlight.js:

This need will disappear with v12, but while the core library is available in both CJS and ES6 module this makes sense.

Is this something we want to move forward with?
