No syntax highlighting for multiple line comments

The comment on lines 2 and 3 is black instead of green

Issue has been around for a while (including on prod!) but for some reason no one quite attended to it

Incorrect syntax highlighting physically hurts my eyes 😢 - Oliver

Unfortunately, updating to the last version of highlight.js (v11.7.0) doesn't seem to fix it.

Style does change slightly though:

On second thoughts, it's probably because of this code in annotations.js

    // Add syntax highlighting to the new code viewer
    $('pre code').each(function () {
      hljs.highlightBlock(this);
    });

I think oliver had a wip branch speedgrader-syntax-fix, it might be worth further investigation

It's mainly because the syntax highlighting is done line by line instead of the whole file
