Rustdoc URL auto-redirect por Peter

https://docs.rs pages are documentation sites for Rust code, and often Google links to a specific version of a page, rather than the latest:
https://docs.rs/crossterm/0.17.1/crossterm/style/struct.Print.html
https://docs.rs/crossterm/latest/crossterm/style/struct.Print.html

This extension automatically changes `0.17.1` to `latest` and reloads the page to that new address.
