Describe your request

Per https://github.com/rust-lang/rust/releases/tag/1.83.0

Describe why this would be a good inclusion for cross

Cross does an excellent job of managing complex compiler toolchains. Looking forward to supporting more of the available Rust targets. I believe Rust application users deserve best in class portable software.
