Syntax highlighting methods

[GuillermoFidalgo]

This maybe more of a question/discussion instead of an issue.
Should we also include the usage of fenced code blocks (i.e. triple backticks ```) in the formatting chapter ?

Also I don't understand what would the

~~~
# my code here
~~~
{: .language-* }

method have over the ``` method?
Is there some additional functionality that it brings ?

I believe the reason was that the Jekyll-based lessons all use kramdown syntax, and at the time the lesson was written, getting the backtick syntax would have required extra configuration (even though that syntax works now). I have a feeling that it was never updated because a) the official documentation never noted the change and b) the lessons would have retained the old syntax, which would have lead to a disconnect between contributors reading the documentation and the presentation of the actual lessons.

That being said, it's certainly possible to add a callout in that episode noting that the ``` syntax is available (though the release of The Carpentries Workbench in May will render this guide obsolete.
