How to reproduce the issue

When running RustLsp openDocs, it fails to redirect to the proper documentation page for certain symbols like macros. When running  openDocs over a ```vec!```, the following page: https://doc.rust-lang.org/stable/alloc/macros/macro.vec.html opens up which is nothing of significance.

Expected behaviour

It should redirect to the page: https://doc.rust-lang.org/std/macro.vec.html and not https://doc.rust-lang.org/stable/alloc/macros/macro.vec.html.

Actual behaviour

Redirects to https://doc.rust-lang.org/stable/alloc/macros/macro.vec.html, which is not information about the macro.

The minimal config used to reproduce this issue.

n/a. Vanilla and latest commit of rustaceanvim.
