Auto merge of #6687 - ehuss:stabilize-wrapper, r=flip1995

Browse source 
Stabilize workspace wrapper.

This fixes it so that `cargo clippy` doesn't share the same cache artifacts as `cargo check`. The Cargo side was stabilized a while ago (https://github.com/rust-lang/cargo/pull/8976), so this should be ready to go. I'm not aware of any blockers or concerns.

Closes #4612

---

changelog: `cargo clippy` no longer shares the same build cache as `cargo check`.
