[bug#52729] [PATCH v2] gnu: ocaml: Update to 4.13.

[pukkamustard]

Hi Julien,

> gnu: ocaml-ppx-tools-versioned: Only build ocaml-4.07 variant.

Any reason for not using the package-with-ocaml4.07 transformation?

> gnu: ocaml: Update to 4.13.

js-of-ocaml and ocaml-dot-merlin-reader are also updated in this
commit. Could they be split to separate commits?

Other than that everything seems to be compiling and working
fine. Thank you very much!
