Should catch cases like #33667 where a dependency was bumped in
Cargo.toml without a corresponding lockfile update. (This can happen
when committing from outside of Zed or if rust-analyzer isn't running.)
Passing `--frozen --workspace` should ensure this doesn't fail just
because there's a newer patch version of some third-party dependency,
and prevent it from taking long.
We only need to run this on macOS because Cargo.lock is
platform-independent.
