Auto merge of rust-lang#12764 - matklad:rustupaction, r=lnicola

Remove deprecate action

https://old.reddit.com/r/rust/comments/vyx4oj/actionsrs_organization_became_unmaintained/

Looking at this holistically, I don't fully understand *why* we need an
action here? Seems like we can just use rustup? nowadays github runners
come with rustup pre-installed.
