Enable windows tests

An alternative to #188

I don't know why they recommended -SwitchLinuxEngine, maybe its an additional (undocumented) flag to -SwitchDaemon.

Let's try with this command:

C:\"Program Files"\Docker\Docker\DockerCli.exe -SwitchDaemon

Let's forget what I said earlier. I tried DockerCli.exe on my local machine, and -SwitchLinuxEngine switches immediately to Linux containers, no restart needed.

Per Github runner windows README Docker is already installed. Maybe because you install Docker via choco, this messes things up.

I was unable to find / run DockerCli.exe without installing Docker CE. Do you know the install path in Windows actions runners?

[adamdecaf]

Linux containers seem to be the default, because when I use -SwitchDaemon there's output about using Windows containers.

I've opened an issue with Github Support on why this isn't working.

I may try to publish windows/amd64 images from emberstack/docker-sftp which is already in C#. Testing against multiple servers is a good idea too.
