🪲 Bug Report - ExpressRoute gateway zone redundancy recommendation and query incomplete

[ejhenry]

Describe the bug

The recommendation and ARG query for zone redundant ExpressRoute gateways does not account for gateways deployed with a PIP in a single zone. Gateways deployed with a single zone PIP are deployed zonally to the same zone as the PIP.

ARPL recommendationId: bbe668b7-eb5c-c746-8b82-70afdedf0cae
APRL recommendation: https://azure.github.io/Azure-Proactive-Resiliency-Library-v2/azure-resources/Network/virtualNetworkGateways/#use-zone-redundant-expressroute-gateway-skus
Public documentation: https://learn.microsoft.com/en-us/azure/vpn-gateway/about-zone-redundant-vnet-gateways#pipzg

The existing query also does not account for the new ERGwScale sku.

To Reproduce

Steps to reproduce the behavior:

1. Deploy virtual network gateway with zonal PIP

Expected behaviour

Query and recommendation should account for scenario where virtual network gateway with zone redundant sku is deployed zonally.
