ci: trigger re-run after smithy host gained cmake + Rust build deps

The previous clippy run on the self-hosted runner failed at
highs-sys build because cmake wasn't on the host. smithy main now
ships the common Rust build-dep set (cmake, clang, lld, perl, m4,
protobuf-compiler, libclang-dev, zlib1g-dev). Pushing an empty
commit to re-trigger CI; clippy should now finish on rust-cpu.
