Code Review

This pull request adds configuration for a new library, google-devicesandservices-health (version 0.0.0), to both .librarian/state.yaml and librarian.yaml. It also introduces an allowed_namespaces list under the Python configuration in librarian.yaml, which includes several Google namespaces such as google.devicesandservices. There are no review comments, and the changes look correct, so I have no feedback to provide.
