This is following the discussion about allowing cargo features to be used in rust-based hooks (started in #3230 continued in #3235).

The cargo add command has been used since 2018 to add dependencies to a rust-based hook's manifest (Cargo.toml). Sometime since then (probably when 2021 edition was stabalized), cargo features were implemented in the cargo install command. As noted in https://github.com/pre-commit/pre-commit/pull/3235#issuecomment-2299164211, this makes cargo install more suitable for a rust-based hook's additional-dependencies because it actually installs additionally specified dependencies.

[!tip] Using --locked better assures expected install behavior. However, this is not the default for cargo install.
