Add Stevedore as an alternative way to install Docker Engine for Windows containers

Disclaimer: I am the author of Stevedore.

Why I think Stevedore is a Good Thing:

1. Consistent behavior for both desktop and server
2. MSI installer is a standard Windows distribution that integrates well into various system administration automation processes.
3. Stevedore provides additional Docker-related tools (Compose, etc) out of the box.
4. Free and open
5. Uses upstream binaries
6. Simple "download, double-click, next-next-next" installation
7. Has automated install ways (Chocolatey, WinGet, Scoop)

Ping? Stevedore recently gained containerd/buildkit/nerdctl support and seems to be the easiest way to set up those on Windows as of today.
