Auto merge of #77336 - pietroalbini:pkgname, r=<try>temp-dev-stable

Always use the Rust version in package names

The format of the tarballs produced by CI is roughly the following:

    {component}-{release}-{target}.{ext}

While on the beta and nightly channels `{release}` is just the channel name, on the stable channel is either the Rust version or the version of the component we're shipping:

    cargo-0.47.0-x86_64-unknown-linux-gnu.tar.xz
    clippy-0.0.212-x86_64-unknown-linux-gnu.tar.xz
    llvm-tools-1.46.0-x86_64-unknown-linux-gnu.tar.xz
    miri-0.1.0-x86_64-unknown-linux-gnu.tar.xz
    rls-1.41.0-x86_64-unknown-linux-gnu.tar.xz
    rust-1.46.0-x86_64-unknown-linux-gnu.tar.xz
    ...

This makes it really hard to get the package URL without having access to the manifest (and there is no manifest on ci-artifacts.rlo), as there is no consistent version number to use.

This PR addresses the problem by always using the Rust version number as `{release}` for the stable channel, regardless of the version number of the component we're shipping. I chose that instead of "stable" to avoid breaking the URL scheme *that* much.

Rustup should not be affected by this change, as it fetches the URLs from the manifest. Unfortunately we don't have a way to test other clients before making a stable release, as this change only affects the stable channel.
