Update version of rustc-std-workspace-* crates

This commit updates the version of the `rustc-std-workspace-*` crates
in-tree which are used in `[patch]`. This will guarantee that Cargo will
select these versions even if minor updates are published to crates.io
because otherwise a newer version on crates.io would be preferred which
misses the point of `[patch]`!
