Added Shelly 2PM Gen 3

[rockflopp]

Hi there, this is my first pull request and all changes were made with the help of GenAI. I had bought new Gen3 Devices which weren't supported yet so I added them to the Adapter and tested it on my smarthomesetup where it worked fine. Please Check with care as this is my first pull request ever.

Thanks

I think I fixed all your change request.

@klein0r weil es um v8.3 Integration des 2pm gen3 geht, frag ich hier direkt mal nach, hoffe das ist ok
beim Upgrade ist mir folgendes aufgefallen, bzw kein Plan ob man diesem Beachtung schenken muss.
