Fix build errors with Rust 1.73.0 (#996)

The recent Rust 1.73.0 release introduced some changes to clippy's
behavior that are causing failures in CI (and correctly calling out
issues in our code). This commit updates the rustworkx source to correct
these failures.

(cherry picked from commit 651409f)
