D10085: copies-rust: remove an unnecessary format!() inside assert!()

REVISION SUMMARY
  The `assert!()` macro supports formatting. Rust 2021 no longer
  supports an unnecessary `format!()` inside it. I noticed because I
  recently update my Rust toolchain and `test-check-cargo-lock.t`
  started failing.
