Add exception: Container registries should use private link [security] [Medium]

[emirgens]

Azure Private Link provides a secure connection between your virtual network and Azure services, eliminating the need for a public IP address. It manages the connectivity over the Azure backbone network. By assigning private endpoints to your container registries, you can prevent data leakage risks. Therefore, we recommend using private link for container registries to ensure secure and private connectivity.
