google_project_alert_policy doc use "name" when code ask "policy"

[jnahelou]

Hello,
In documentation policy looks like

    describe google_project_alert_policy(name: 'projects/spaterson-project/alertPolicies/9271751234503117449') do
      it { should exist }
    end

When code wait for policy argument :

@policy = @gcp.gcp_client(Google::Apis::MonitoringV3::MonitoringService).get_project_alert_policy(opts[:policy])
