rust: Implement Display instead of ToString for enums (#19611)

Browse Source 
Rust docs for `ToString` explicitly recommend implementing `Display`:

> This trait is automatically implemented for any type which implements the Display trait. As such, ToString shouldn’t be implemented directly: Display should be implemented instead, and you get the ToString implementation for free.

See: https://doc.rust-lang.org/std/string/trait.ToString.html
See: https://github.com/Nitrokey/nethsm-sdk-rs/pull/33
