[Dependencies] - Manifest validation errors with msstore package identifier

Brief description of your issue

Some packages may depend on programs from the Microsoft Store like Xbox Game Bar. Adding these packages as dependencies throws a manifest validation error. Ignoring the validation error, the dependencies install correctly

  PackageDependencies:

Expected behavior

Manifest validation to succeed
