[appstore] fix invalid country code for Serbia

* sr-SR is not a country code that Microsoft accepts (and from what I can see
  is not valid, because it should be sr-RS).
* This has the unfortunate effect of preventing the installation of Rufus from
  the Windows Store, which fails with error 0x80070057 (Invalid parameter).
* Fix this by using a country code for Serbia that Microsoft does accept: sr-Latn-RS
* Closes #2015
