fix(docker): expose git service's 2222 through 0.0.0.0

Other ports we use are locked to 127.0.0.1. The `git` service,
however, already promotes security in its sshd service and
can't really be abused from an external source. This simplifies
the need to forward to localhost if deploy targets want the sshd
to be available.
