Automatically publish .msix packages in /releases.

[RokeJulianLockhart]

1. Proposition

   Automatically package installers for this software as MSIX or MSIX Core (as necessity dictates) rather than as .MSI or .exe.

2. Rationale

   Summarily, MSIX is the format that Microsoft has designed to replace MSI and APPX, and is consequently easy to manage via https://github.com/microsoft/winget-cli.git and the Microsoft Store, leaves no trace when uninstalled, and is entirely supported by Windows 10, 11, and is the sole format supported by Windows IoT. https://learn.microsoft.com/windows/msix/overview explains more.

   However, verbosely:

   1. This would allow installation to be much more easy for users of Windows 7 and Windows 8.1, because of MSIX Core, and for Windows 10 and Windows 11 because of their native support of .msix.
   2. This would allow installation by package-managers that are similar to https://github.com/microsoft/winget-cli to install packages without the possibility of corruption that execution of the current installer is able to cause every time that the package is replaced during replacement.
   3. This shall allow people that are forced to utilize Windows 10 S to utilize this via their devices without worrying that their method of installation is not supported. It is additionally a significantly more standardized method of installation than .exe, .msi, and .appx files.
   4. This shall allow for superior management of automation, and shall allow for a single code-base to be utilized for every distribution of Windows that is supportive of the Universal Windows Platform, such as all of the derivatives of Windows 10 and Windows 11.
