Elasticache Redis v7 doesn't support "new" notify-keyspace-events parameter value

Redis version 7 now offers a "new" n notification for keyspace events. But using this value for the notify-keyspace-events parameter in a redis7 parameter group returns error: invalid parameter value for notify-keyspace-events, allowed characters are 'EKg$lshzxeA'.

Could the Elasticache product team please add n, and m to the allowed characters for this parameter? 😄 Thanks.
