CI: Cargo build getting stuck

[cobward]

PRs to the repo aren't building, cargo build is hanging. There are also clippy warns that don't appear when running it locally, for example:

error: field is never read: `task`
   --> src/orbit.rs:150:5
    |
150 |     task: Arc<AbortOnDrop<()>>,
    |     ^^^^^^^^^^^^^^^^^^^^^^^^^^
    |
    = note: `-D dead-code` implied by `-D warnings`

So far I've identified the issue to be present in cargo with version 1.57.0, but not 1.56.0.

The issue is present in stable and beta (1.57 and 1.58) but appears to be fixed in nightly. This might be the issue (thanks @sbihel): rust-lang/rust#89195
