Specifying docker_host_url does not work

[tomhughes]

👻 Brief Description

Specifying docker_host_url in the configuration does not work because dokken still tries to connect to the default docker and errors our when that fails.

Version

kitchen-dokken 2.20.3

Environment

Fedora 39

Scenario

Trying to use a user podman instance as the docker implementation.

Steps to Reproduce

Specify the URL as follows:

driver:
  name: dokken
  docker_host_url: unix:///run/user/1000/podman/podman.sock

Expected Result

It works.

Actual Result

It errors out trying to make a TCP connection to docker:

kitchen-dokken could not connect to the docker host at tcp://127.0.0.1:2375. Is docker running?

➕ Additional context

The code at

kitchen-dokken/lib/kitchen/driver/dokken.rb

Line 48 in 1035b97

default_config :docker_info, docker_info

causes docker_info to be called which tries to make a connection to default_docker_host which errors out.
