Update GCP-VPC-Flow-logs-for-the-subnet-is-set-to-Off.json

[jcallowaypanw]

Per KeyBank:

Justification:

Google documentation states that flow logging is not supported for GLOBAL_MANAGED_PROXY also.

Per Google documentation (Terraform Registry ):

Flow logging isn't supported if the subnet purpose field is set to subnetwork is REGIONAL_MANAGED_PROXY or GLOBAL_MANAGED_PROXY

Note that INTERNAL_LOAD_BALANCER is fine to keep in the RQL for backward compatibility, but it is no longer a valid value and was changed to REGIONAL_MANAGED_PROXY. See https://cloud.google.com/load-balancing/docs/proxy-only-subnets#migrate-purpose
