Hi! I have a Prometheus-server. Recently I was unable to get some confirmation of completion alerts.  
In the logs I found the following entries  
`ts=2024-05-22T00:43:20.200Z caller=notifier.go:369 level=warn component=notifier msg="Alert batch larger than queue capacity, dropping alerts" num_dropped=797`  
In theory I know it is possible to extend alertmanager.notification-queue-capacity by flag.  
But is it possible to extend this parameter via a configuration file?
