[ci] no need for the windows generator

[simogasp]

Build was failing on Windows due to the switch to the new version of windows latest.
When using vcpkg, there is no need to explicitly specify the generator and the architecture; it will be resolved automatically.

Code Review

This pull request removes the explicit Visual Studio generator and the build type configuration from the CMake commands in the Windows build script. The feedback correctly points out that removing the build type configuration can cause issues with single-configuration generators like Ninja, where the build type must be specified during the configuration step.

Removing -DCMAKE_BUILD_TYPE="$BuildType" can cause issues if CMake resolves to a single-configuration generator (such as Ninja). For single-configuration generators, the build type must be specified during the configuration step; otherwise, it defaults to Debug or empty, and subsequent build commands (e.g., cmake --build . --config $BuildType) will not build the expected configuration. It is safer to keep this flag to ensure compatibility with both single-config and multi-config generators.
