fix at Docker-module.md

[ciril88]

Hello,

Nice guide, i found 1 error at playbook docker_play.yml
- name: Install required system packages tags: install apt: pkg: - apt-transport-https - ca-certificates - curl - software-properties-common - python3-pip - virtualenv - python3-setuptools **- pipx - python3-docker**
I have to add pipx and pythond3-docker after that i comment lines:
# - name: Install Docker Module for Python # tags: install # pip: # name: docker
Best regards
Ciril
