📙 Update apple auth adapter key

What is the issue?
It is mentioning that you can use client_id. That might have been true in the past, but now the correct way is to use clientId.

Can you propose a solution?
Correction to:

{
  auth: {
   apple: {
     clientId: "my_apple_service_identifier", // optional; provides extra validation; replace with your Service ID provided by Apple
   }
  }
}

I looked into it a bit more and I am unsure about the comment for the clientId parameter.

The comment suggests to use the "Service ID", but it seems to be the app bundle ID that should be used, see
