Code Review

This pull request bumps the version in librarian.yaml, reorganizes and cleans up imports in the google-cloud-bigtable package, updates docstring link formatting in the google-cloud-billing package, and reformats docstrings in the google-devicesandservices-health package. No review comments were provided, so there is no additional feedback.
