Description

Edited docs/stylus/quickstart.mdx

rust-toolchain.toml is auto generated with cargo stylus new so the cat command step is no longer needed. Along with removing the WASM build target step since running a cargo stylus commands will install wasm32-unknown-unknown if not detected (not 100% sure but I fiddled around a lot with commands and removing the build target and it would re install it on its own without hitting errors)

Also changed the order in which the information was presented, now it says to run cargo stylus --help right after running cargo install --force cargo-stylus to check if the install was successful instead of trying to create a new project via cargo stylus new and then running cargo stylus --help
