Lock google, google-beta provider version to ~> 1.20

The google and google-beta providers are causing some issues with the
simple-regional-private example; these issues in turn are causing CI to
fail for all recent pull requests. This commit repairs CI by pinning the
version of the google and google-beta providers; we can address v2.0
support in the future.
