Add crate documentation for the Rust crate of rz-pipe

[officialcjunior]

Description

Create an documentation page for rz-pipe's Rust crate, just like r2pipe's one and host it when rizin.re/docs is up.

It says Page not found. Is this issue closed ?

It's not closed, but largely irrelevant since Rizin provides C API that can be used with rust-bindgen, which is more granular and more like normal libraries are used.
