docs: Replace relative URL by Rust item links

Some links in the documenation are broken. `cargo doc` will resolve item names when used in markdown links. The tool will report unresolved links as warning so that they can be fixed. Replace any relative URL by such item link. See https://doc.rust-lang.org/rustdoc/write-documentation/linking-to-items-by-name.html
