--destination-name parameter is not optional during first time setup of capture for eventhub

### Describe the bug

--destination-name parameter is not optional during first time setup of capture for eventhub.
and not adding that in command results in poor error which doesn't even hints that create/update eventhub failed due to not specifying --destination-name .

az eventhubs eventhub create --name azcaptureeh --namespace-name ambhatiaehbdr --resource-group ambhatiaehbrg --enable-capture true --storage-account "/subscriptions/1da6539d-2c29-426a-b770-230f4ed67a93/resourceGroups/ambhatiatempstgrg/providers/Microsoft.Storage/storageAccounts/ambhatiatempstg"
