Un-deprecate rust-toolchain-version or alternative? #2019
Description
By default dist will use the GHA runner's default cargo version, which may be a version or two behind the latest stable. Using rust-toolchain-version will add a step that installs and forces the provided rust toolchain version. However it is deprecated, asking users to use the rust-toolchain.toml file.
My problem is that I develop locally using the nightly toolchain, and would like to release binaries using stable. I don't want developers to be forced to use a stable rust-toolchain if they use nightly locally like I do, because it usually just breaks any command if for example ~/.cargo/config.toml contains nightly-only configs.
Ideally I can keep using rust-toolchain-version, or alternatively I'd inject a single step like rustup update stable && rustup default stable (if this is not already possible). What do you think? Thanks!
