fix: Remove unused variables regarding listener ARNs count

The following variables have been removed from upstream module
`cloudposse/alb-ingress/aws`, and stopped being used since `v0.58.0`
[1]:

* `alb_ingress_unauthenticated_listener_arns_count`
* `alb_ingress_authenticated_listener_arns_count`
