[FEATURE] Add Terraform support for azurerm_resource_group

### Your suggestion

Using `azurerm_resource_group` along side `azapi` resources is common in Microsoft Learn docs and AVM.

Let's add support for this resource type because it has a relatively low number of properties that can be configured.
