Update Nest doorbell event to use standard DoorbellEventType.RING

[allenporter]

Breaking change

If you are currently using the Event Entity event type doorbell_chime, you need to replace it with the new standardized event ring.
This change intends to standardize the event type across different integrations, so they can be seamlessly used in the new triggers and conditions.

Event types for device triggers are not changed.

Proposed change

Update Nest Doorbell event entity to use the standard new event type.

Doorbell event entities now have a standard ring event type. Integrations that use EventDeviceClass.DOORBELL must include DoorbellEventType.RING in their event_types list.
