ci: switch Docker to Linux engine on Windows before Kind cluster setup

Kind requires Linux containers. On windows-latest, Docker Desktop
defaults to Windows containers mode causing Kind to fail with
'npipe:////./pipe/docker_engine: The system cannot find the file'.
Add a step to call DockerCli.exe -SwitchLinuxEngine and wait for the
daemon to be ready before cluster creation.
