`diff` language is not supported

[poliorcetics]

Github supports code blocks with diff as the language, like so:

/// See [`Rotation`]
///
- /// [`Rotation`]: struct.Rotation.html

- /// See [`Rotation`](struct.Rotation.html)
+ /// See [`Rotation`]

This is not the case on the published version of `wool, it is possible to add it ?

Ah, this seems because Prism uses a separate plugin. Try adding the script to template.rs.
