The properties in the returned object of deployment() is confusing

The properties in the returned object of deployment() will differ based on whether the deployment object is passed as a link or as an in-line object.
It does not make sense because you don't know which way the deployment object is passed. For example, if customers deploy it on Azure Portal, the invalid "templateLink" will break the deployment.

Compare the properties returned by deployment() when the deployment object is passed as a link versus as an inline object. Determine a consistent result that works for Azure Portal deployments and does not expose an invalid templateLink; the issue is done when both input forms produce compatible properties.
