PIP Availability Zones not available in all regions

[Phydeauxman]

Description
Public IP Address resources created by Terraform default to using Zone-Redundant for the Availability-Zone parameter. Availability zones are not available in all regions so when attempting to create a Public IP Address as part of a deployment to a region where Availability Zones are not supported, the deployment fails.

Steps to Reproduce
Steps to reproduce the behavior:

1. Attempt MLZ deployment to West US region in Commercial

Expected behavior
Deployment is successful

Actual behavior
Deployment fails with error stating that region does not support availability zones

@Phydeauxman pointed us to availability_zone = No-Zone for setting this regardless of cloud or region availability https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/public_ip#availability_zone

To add to the Firewall PIP, the Bastion PIP requires updating to availability_zone = No-Zone too
