[Windows Arm64] Also use Windows 11 for Devicelab tests (flutter#134082)

Currently, the Windows Arm64 tests try to run on Windows 10 devices.
However, [all Windows Arm64 devices use Windows
11](https://chromium-swarm.appspot.com/botlist?c=id&c=task&c=os&c=status&d=asc&f=cpu%3Aarm64&f=os%3AWindows-11&f=pool%3Aluci.flutter.staging&s=id)
which result in the Windows Arm64 tests not running. This updates the
configuration to accept both Windows 10 and 11 (ideally the tests would
run on both OSes).
