CI uses archived GitHub Action

CI uses [`actions-rs/clippy-check`](https://github.com/actions-rs/clippy-check):
https://github.com/google/googletest-rust/blob/75ed7ee08cbf1928d5ce2dabc5233cd40be63ee0/.github/workflows/ci.yml#L38

however the whole `action-rs` org has been archived since 2023. accordingly you should eventually migrate to something else
