Disable public network access to API App Service - traffic is routed through PE from App Gateway

[jonnyry]

Resolves #3986

What is being addressed

Disable public network access to the API App Service - Web traffic should come via the App Gateway and not direct. App Gateway uses a PE to communicate with the API App Service and therefore does not need a public endpoint.
