Find a New Home for the "Portability" Page from v2.ocaml.org

On https://v2.ocaml.org/learn/portability.html, we have a page "Portability".

This information needs a new home on the current ocaml.org site.

I support adding it to the Platform Tools section. It is a focus on a tool, the compiler.

Indeed, that's an embarrassing oversight on my part, it's very important information to have on the site!

I agree with @cuihtlauac, the Platform section looks like a good place for this. There will be differences between what the compiler supports, the Platform tools and the opam infrastructure, so we might want to add the information for the platform tools and the infra as well.

Ok, so then this can go in Platform Tools > Compiler > Portability.
