HTML in Preformatted code is rendered in docs page

[avestura]

Even though <!-- $MDX skip --> exists on top of the pre-formatted text in documentation, the HTML is being rendered in the output.

For example:

https://github.com/ocaml/ocaml.org/blob/main/data/tutorials/lg_01_functional_programming.md?plain=1#L440-L453

This is how the markdown should look like (Github's readme screenshot):

This is what it looks like now (ocaml.org/docs screenshot):

Omd should probably escape the special characters when transforming the document to HTML. cc @tatchi

Hilite is the faulty component.

Removing highlighting removes colors and faulty behaviour
