[bug#69185] [PATCH master] gnu: ocaml: Update to 5.1.1

[pukkamustard]

Thanks!

I wonder how useful the OCaml compiler itself is without a
`package-with-ocaml5.1` transformation? The `ocaml` package itself just
provides the compiler but no nice way (afaik) of using the compiler with
dependencies and all. Do you think it would make sense to add a
`package-with-ocaml5.1` transformation in `(guix build-system ocaml)`?

Maybe even better we can replace the OCaml 5.0 compiler with a newer
version. The only packages depending on ocaml-5.0 are ocaml5.0-merlin
and ocaml5.0-eio. They could be updated to use a newer OCaml
version. Maybe no point in keeping OCaml 5.0 around. What do you think?
