Add the ability to show highlighted lines in the code editor

Other tutorials have a nice feature of showing which lines change between the different versions of code snippets.

Here is an example from the Next JS tutorial.

Do you mean when the code editor has static content, or also in an editable code editor?

Either could be possibly be useful, but it probably makes the most sense to start with the static version. I don't think it would be too unintuitive if the highlights disappeared as you modified an editable one that started out with highlights.
