* 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
* Having two separate Visual Studio solution files, while more convenient, was a major
pain in the ass and it also required us to update versioning in the .appxmanifest for
each commit.
* Also, this new AppStore build process enables us to use the GitHub Actions executables
to further foster the complete transparency of our build process.
