Enable App Installer Allowed Zones for MSIX Packages

This policy controls whether App Installer allows installing packages originating from specific URL Zones. A package's origin is determined by its URI and whether a Mart-of-the-Web (MotW) is present. If multiple URIs are involved, all of them are considered; for example, when using a .appinstaller file that involves redirection. If you enable this policy, users will be able to install MSIX packages according to the configuration for each zone. If you disable or do not configure this policy, users will be able to install MSIX packages from any zone except for Untrusted.
