Code Review
This pull request updates the documentation to include rust-toolchain.toml as a supported idiomatic version file for Rust. Feedback suggests improving the underlying implementation by supporting the extensionless rust-toolchain filename, handling plain-text version files for better compatibility with rustup, and replacing unwrap() calls with safer parsing to prevent potential panics.

While adding rust-toolchain.toml to the documentation is correct, there are a few points regarding the implementation in src/plugins/core/rust.rs that should be addressed to ensure a robust experience:
- Support for
rust-toolchain:rustupalso supports therust-toolchainfilename (without the.tomlextension). It would be more idiomatic to support and document both. - Robust Parsing: The
parse_idiomatic_filefunction insrc/plugins/core/rust.rsuses several.unwrap()calls (e.g., lines 299, 302, 307, 309, 318, 320). If the TOML file has an unexpected structure (e.g.,channelis not a string),misewill panic. It would be safer to useas_str()andas_array()with proper error handling. - Plain-text Support:
rustupsupportsrust-toolchainfiles that are just a plain string containing the channel name. The current implementation only supports TOML. Supporting plain-text would improve compatibility.
