Doorbell Timeouts
<!-- BUG REPORTS THAT ARE NOT FILLED OUT COMPLETELY WILL BE CLOSED AUTOMATICALLY WITHOUT WARNING AND WILL NOT RECEIVE A RESPONSE. THE FORM IS HERE FOR A REASON. :). -->
<!-- Please ensure you read the documentation before creating a support request, especially the Troubleshooting page. -->

**Describe The Problem:**
<!-- A clear and concise description of what the issue is. -->
The G4 Doorbell firmware 4.41.16 seems to cause it to respond slightly more slowly, particularly after a period of inactivity.  This causes timeouts when HomeKit tries to retrieve the snapshot image and so all other cameras update their snapshots, but the doorbell does not.

Raising PROTECT_API_TIMEOUT from 3.5 to 5 seems to give the Doorbell with this new firmware time to respond.

**To Reproduce:**
<!-- Steps to reproduce the behavior. -->
Update Doorbell to current latest firmware 4.41.16.  Don't check it for a while to let it idle, then open Home.app on iOS, iPad OS or macOS.  The Doorbell image will not update with the default 3.5 timeout.  The logs will show the API timeout and the snapshot retrieval failure.
