build: use code-suggester v5 (googleapis#31553)

* build: use code-suggester v5

Unfortunately a manual run of the generation action against https://github.com/googleapis/google-api-java-client-services/pull/31118/changes ended up with googleapis@a7acc0e, which transferred the changes directly.

This PR reverts the changes and additionally tries code-suggester v5

* chore: remove comment
