This version introduces support for (self-hosted) Windows/ARM64
There is a convenient Azure Resource Manager template to easily set up a Windows/ARM64 VM on Azure and register it as a self-hosted runner for GitHub Actions.
With this version of setup-git-for-windows-sdk, it is possible to target such runners by configuring the architecture to aarch64. This
will install a hybrid SDK: most of the base packages are x86_64 ones and will run using Windows 11's emulation. But the clang toolchain is
fully aarch64 and ready to build aarch64 executables, too.
Better support for self-hosted runners
By configuring cleanup: true for this Action, the SDK that is set up will automatically be torn down at the end of the GitHub workflow run.
