Implement fallback to Rouge for languages not supported by Highlight.js (and track usage)
As part of moving to Highlight.js for highlighting source code we need to implement a fallback to Rouge (the old way of highlighting source code) for languages that Highlight.js does not support, and track the usage of the fallback.
This will ensure our transition to Highlight.js is smooth and give us a better understanding of how often the fallback is used (also track the language as part of the tracking event if possible?)
