Docker Engine 23.0+ Error Issue

As of this morning, the latest Docker release (23.0) caused issues with the docker-machine fork, resulting in GitLab Runner not being able to create autoscaling runners using the docker+machine executor. The issue is captured in #98 (closed). Many of us were using an older version of docker-machine as a workaround for the problem described in this issue, but since we now have to update to the latest release this is no longer possible.
