`winget list --scope=machine` throws `0x80070005 : unknown error` when non-admin

Brief description of your issue

When winget list is used with the scope=machine in a non-admin context, instead of telling the user that they need admin it throws a red hot 0x80070005 : unknown error message

Steps to reproduce

Open a non-admin command prompt (tested in CMD.exe and Terminal/PowerShell) and run
winget list --scope=machine

Result:

Failed to open the predefined source; please report to winget maintainers.
An unexpected error occurred while executing the command:
0x80070005 : unknown error

Expected behavior

Something that is not unknown error? A meaningful error message that the user needs admin rights?

Actual behavior

Failed to open the predefined source; please report to winget maintainers.
An unexpected error occurred while executing the command:
0x80070005 : unknown error

Start at the list command entry point and the logged PredefinedInstalledSource creation, reproducing the non-admin --scope=machine case. Trace how access denial (0x80070005) becomes the CLI's unknown error; done means the command reports that administrator rights are required instead.
