feat: rust toolchain file

[EstebanBorai]

Provides a Toolchain File to control Rust version to use,
currently the file points to Nightly Latest.

This facilitates contributors when running commands like

cargo +nightly fmt

This is an update from: #643

Thanks!! @EstebanBorai Interesting stuff. Basically, this config will force cargo fmt and cargo clippy to execute the respective component in nightly version.
