MSI for Win10 does not have working Notification

[saifelse]

• Version: v20.13.3

• Target: msi, win10 (x64)
  According to this thread Notification API do not work with Windows 10 16299.19 (fall creators update) electron/electron#10864 (comment) Win10 has the same problem as Win8 where a shortcut file with a reference to the appId must be placed in the start menu.

In the PR to follow, I've confirmed that adding app.setAppUserModelId(appId), along with such a shortcut configured in the WXS file causes new Notification(...).show() to work in at least Win10.

"A shortcut to your app, with a System.AppUserModel.ID, must be installed to the Start screen. Note, however, that it does not need to be pinned to the Start screen. For more information, see How to enable desktop toast notifications through an AppUserModelID."
