Passing resource JSON for invocation no longer works

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Summary

dsc resource get -r is expected to accept a wildcard, name of resource, or the resource JSON (to avoid a search). The latter has been broken.

Steps to reproduce

$osinfo = dsc resource list Microsoft/OSInfo
dsc resource get -r $osinfo

Expected behavior

Since `$osinfo` is a JSON representation of a resource, it has all the info about the resource so discovery should not occur and `dsc` should try to directly perform a `get`

Actual behavior

`dsc` is using the JSON as a search string

Start at the dsc resource get -r argument handling and reproduce the issue with the PowerShell commands in the report. Trace how the JSON from dsc resource list Microsoft/OSInfo is classified, then verify that passing it avoids discovery and performs the resource get directly.
