Auto merge of rust-lang#120454 - clubby789:cargo-update, r=Nilstrieb

bors · bors · commit a2b0c4b30caf · 2024-02-14T00:03:43.000Z
`cargo update` Run `cargo update`, with some pinning and fixes necessitated by that. This *should* unblock rust-lang#112865 There's a couple of places where I only pinned a dependency in one location - this seems like a bit of a hack, but better than duplicating the FIXME across all `Cargo.toml` where a dependency is introduced. cc `@Nilstrieb`
