OCPBUGS-48827: aws/edge/byovpc: tag edge subnets with shared value

Previously the subnets created by user (BYO VPC) on edge zones (Local or
Wavelength zones) were not tagged with
kubernetes.io/cluster/<InfraID>:shared.

This change ensures installer is also setting the same cluster tag as
regular zones.
