the value of ELB subnet tag should be 1 or empty, not true

To make AWS Load Balancer Operator work on HyperShift, one of the requirements is the ELB tag should be set on subnets. see https://github.com/openshift/aws-load-balancer-operator/blob/main/docs/prerequisites.md#vpc-and-subnets   

The value of `kubernetes.io/role/elb` or `kubernetes.io/role/internal-elb`should be 1 or ``. 

but from the code below, hypershift uses "true"
