Fix WinGet release workflow to account for new installation matrix (#718)

Update the WinGet release workflow to match the updating manifest in
`microsoft/winget-pkgs`, where there are now four installation options:

- x86_64 / x64 with machine scope
- x86_64 / x64 with user scope
- aarch64 / arm64 with machine scope
- aarch64 / arm64 with user scope
