List trait impls before deref methods in doc's sidebar

This PR is acting directly on a suggestion made by `````@jyn514````` in rust-lang#83133. I've tested the changes locally, and can confirm that it does in fact properly achieve what he thought it would. This PR also in turn closes rust-lang#83133.
