Subject: [PATCH] jquery: Fix CSS to account for the newest highlight.js

Since for some time some sites will use an older version of
`grunt-jquery-content` that includes an older highlight.js version, for now both
types of CSS rules need to be present. The legacy ones have been marked with
comments.

The new version of highlight.js uses more generic class names, shared between
languages. That means there's no 1-1 correspondence between the old & the new
ones in all cases & some differences in syntax highlighting will be there.

That's 9 years of highlight.js updates, though!
