Update rust-toolchain to new toml syntax This allows us to completely skip the "Install Rust" step in CI because the rust-toolchain file completely describes what we need. The first invocation of cargo will simply install all the required components. Additionally, we make all caches dependant on the version of Rust that we require. 2021-02-17 03:55:53 +00:00			`[toolchain]`
