Bump cargo for rust-lang/cargo#4000 rust-lang/cargo#4000 recently landed, which fixes warnings about using `-Z` when `CARGO_INCREMENTAL` is set while running stable/beta builds. As #41751 has now landed, these warnings will turn to errors in the next release, so getting the cargo fix in place is necessary unless we want people confused about why they can no longer compile anything on stable/beta.
