Fix winget show completions (#1091)

Update `winget show` completions according to official docs at
https://learn.microsoft.com/en-us/windows/package-manager/winget/show

Sort flags like official documentation.

Remove multiple flags which seemingly come from `winget install`;
presumably a copy-paste error when originally implementing this command.
