Issue description

Shouldnt the OnOff cluster be on Endpoint 1 not Endpoint 3 in the Matter light example?

Is there a reason why the OnOff cluster for the Matter light example is on endpoint 3 rather than endpoint 1? see libraries/Matter/examples/matter_lightbulb/matter_lightbulb.ino

I am testing with the chip-tool and after pair I am trying to interact with the OnOff cluster. In most other Matter development platforms that primary device type clusters are on endpoint 1. But i have found that any matter example that I have tried from this repo the primary clusters are on Endpoint 3.

Am I missing something?
