Update brokered connection example in event-hubs-tier-limits.md

Updated the example under "Number of brokered connections per namespace" to better fit the scaling of Event Hub Premium (from 3 to 4). As per https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-scalability#processing-units "You can purchase 1, 2, 4, 6, 8, 10, 12, or 16 processing Units for each Event Hubs Premium namespace"
