Align Google Assistant & Cloud config

I’m switching to the cloud implementation of Google Assistant due to some issues with the setup, and noticed that the configuration isn’t the same for the Google Assistant component (https://www.home-assistant.io/components/google_assistant/) as for the Google Assistant part of the cloud component (https://www.home-assistant.io/cloud/google_assistant/).

I thought I could just reference the existing block of entities in the cloud part, but it seems that doesn’t work, since the component has an additional expose variable for each entity.
