Replace nursery links with rust-lang links

Both repos have been moved to the `rust-lang` org and the links are
still redirecting properly. This way we just avoid the redirect and make
the link shorter.

 4. `bindgen` will produce the generated Rust code to the output of the terminal window. This file may be piped to a file in your project, such as `bindings.rs`. You may use this file in your Rust project to interact with C/C++ code compiled and linked as an external library. Tip: don't forget to use the [`cty`](https://crates.io/crates/cty) crate if your types in the generated bindings are prefixed with `cty`.
