Show WinGet and just-install packages

[Rioluuu]

Right now winfetch only shows packages which are installed from Chocolatey or Scoop. I think it would also be a good idea to show all the WinGet packages in winfetch.

In WinGet you can view the list of installed packages/apps using winget list.

just-install might also be a future goal.

winget package count can be calculated by

(winget list | Measure-Object).Count - 4

But the tricky part is that this counts all packages ever installed, not just those installed by winget itself. winget-only list is being tracked here microsoft/winget-cli#964.

To be honest, I'd like to see all packages ever installed. It's also WinGets goal to import all the "packages" which were originally installed the "classical way".
