[Lint] report warning if resource type key is not read-only in ResourceCreateOrReplace template

[MaryGao]

As we offlined discussed this is a real case in contentsafety , for Azure template ResourceCreateOrReplace it would lift the key properties to method level as path parameters, so there would exist duplications between path paramter and request body property and it's better to add a linter to limit the key property as read-only so that we could guide spec author without duplications.
