* chore: fix dependencies in java-dataproc

This PR fixes java-dataproc by changing its `gprc-google-iam-v1`
to test-scoped. This however brings a compilation error because
the proto classes transitively brought by the mentioned dependency
are not available anymore. This is fixed by additionally bringing
the `proto-google-iam-v1` as compile-scoped.
