[RS] Add Gateway Resource

[badeamarjieh]

📝 Description

When I am automating and managing data analytics infrastructure using Microsoft Fabric across multiple environments,
I want to provision and configure Gateways as code in Terraform,
So I can consistently and securely manage my data connectivity resources, ensure repeatable deployments, and streamline updates in a single Infrastructure-as-Code workflow.
