e2e: fix windows client docker (hashicorp#17572)

the windows docker install script stopped working.

after trying various things to fix the script,
I opted instead for a base image that comes with
docker already installed.

error output during build was:
  Installing Docker.
  WARNING: Cannot find path 'C:\Users\Administrator\AppData\Local\Temp\DockerMsftProvider\DockerDefault_DockerSearchIndex.json' because it does not exist.
  WARNING: Cannot bind argument to parameter 'downloadURL' because it is an empty string.
  WARNING: The property 'AbsoluteUri' cannot be found on this object. Verify that the property exists.
  WARNING: The property 'RequestMessage' cannot be found on this object. Verify that the property exists.
  Failed to install Docker.
  Install-Package : No match was found for the specified search criteria and package name 'docker'.
