style: clippy fix manual_is_multiple_of

NOTE: This method was added in a recent version of Rust (1.87.0), so
changing to this code means that our minimum supported Rust version
would become that! If you'd rather keep compatibility with
older-than-stable versions of Rust, we should leave this unchanged!
