* '.wic' are DD images used by the Yocto project.
* Why Yocto chose to use their own extension instead of using the de-facto '.img' is beyond me but hey...
* Also update GitHub Actions dependencies to latest.
* Closes#2319.
* With the removal of Windows 7 support, wrong platform archs in the check for updates
(that has now been fixed) and switch to an x86_64 default MinGW binary, we have enough
breaking changes to warrant a version bump for the major. So just do that.
* Also fix a couple Coverity warnings and update a URL.
* Remove last ditch effort on systems that are clearly broken for localization
and always report an explicit error to the user.
* Also update GitHub Actions actions/checkout (Closes#2036).
