Rust installation command doesn't install toolchain or targets

[sisou]

According to https://wasix.org/docs/language-guide/rust/installation, I only have to run cargo install cargo-wasix. However, that does not install the rustup toolchain or targets, as the documentation suggests. In fact, running rustup toolchain list afterwards does not show anything wasix-related.

My versions:

> cargo wasix --version
cargo-wasix 0.1.23

> cargo --version          
cargo 1.74.0 (ecb9851af 2023-10-18)

> rustc --version 
rustc 1.74.0 (79e9716c9 2023-11-13)

> rustup --version          
rustup 1.26.0 (5af9b9484 2023-04-05)
