`updater > windows > installerArgs` should be spilt up now with multiple updater types

### Describe the bug

With https://github.com/tauri-apps/plugins-workspace/pull/2624, we can now have multiple Windows updaters at the same time, and the `installerArgs` should be split up to support each cases separately

Our `app-updater` test for the .msi installer doesn't work right now because it is passed a `/NS` arg (fixed in 61134385dc8db11f11616054d9bcac9a5e23e024)
