failed on following the "Getting Started" docs because `wasm32-wasi` is not installed automatically.

Hi team!

I am exploring the fluence and trying to build my first application on it.

I followed this doc: https://fluence.dev/docs/build/overview/getting_started

I get lots of build errors because I already get rust setup up on my machine but wasm32-wasi support is not installed by default.

I saw some codes to setup rust but I think maybe my situation is not covered.
