Missing math formatting in documentation pages

[gadmm]

The following page uses the math feature of odoc backed by katex: https://ocaml.org/p/memprof-limits/0.2.1/doc/statistical.html.
As you might see, the maths aren't currently displayed.

Depending on your odoc version this might be related to ocaml/odoc#1092

The problem is still there (https://ocaml.org/p/memprof-limits/latest/doc/statistical.html). The problem seems to be that the katex script is not included and loaded in the generated html.
