Dart code now supports the full flow that the C++ code used to: version check, download, replace app bundle. Bonus: the Dart code is much easier to follow, thanks to async/await! This is part 2 of a 3-part change. The first part added new mojom interfaces, PathService and UpdateService, to the sky_services package.
