RDP does not support platforms other than Windows

[ed6767]

Describe the bug

Trying to run any RDP connection on Darwin or Linux results in the RDP connection is not supported for this platform. Supported platforms: Windows error, even when the official Microsoft RDP client is installed.

Expected behavior

On macOS and many Linux repos, the RDP client can be opened via the RDP URI format. This seems to be an arbitrary restriction to the RDP feature. The CLI should at least attempt to start an RDP connection, or offer an RDP URL, especially considering not everyone wants to use the default RDP client
