Description

Although i'm not sure why the resource needs it's own resource type, other backup vault policies all have it's own resource type, so requesting to add it here. If it's not needed i can also add the resource in the terraform-azurerm-caf module without an azurecaf_name

Does this introduce a breaking change

• [ ] YES
• [x] NO
