GitHub Actions workflow cannot build arm32 after updating Windows SDK (#1454)

arm32 is not supported anymore by Windows. There has not been a native arm32 OS since before Win11. The wow32 backcompat on arm64 devices to run arm32 programs was removed with Win11 24H2. Most notably, the ability to build arm32 with newer SDKs and toolsets has seemingly been removed. This is now breaking the CI build.

The easiest fix is to simply remove arm32 support.
