using wrong port in WSL

[johrstrom]

I have a project using a configuration below to use port 2222 instead of port 22. I currently use WSL to do local development (it works on through the github CI).

Currently when I run this on WSL, it tries to use port 22 instead of port 2222.

    docker_port_bindings:
      22/tcp:
        - HostPort: '2222'
          HostIp: '127.0.0.1'

If I comment out the || ENV.fetch('WSLENV', nil) statement below it works fine.

beaker-docker/lib/beaker/hypervisor/docker.rb

Lines 128 to 130 in 299b9c0

	def nested_docker?
	ENV['DOCKER_IN_DOCKER'] || ENV.fetch('WSLENV', nil)
	end

I'm not 100% sure why WSL is being treated as the same as nested docker, but I don't think it should be. Seems to me that you should have a wsl? check for IP issues specifically.

Happy to try to supply a patch, but I'm not clear on what #56 solved.

Expected behavior
When specifying HostPort 2222, it should use port 2222.

Actual behavior
It continues to use port 22 instead of 2222.

Versions tested
2.6.0.

Also happy to supply additional information as required. I hacked the source with all sorts of puts statements to see when/how port22 is being modified so I'm happy to share any of that information.
