Installing of bash completion on Debian Buster failed when docker_version is set

[frzb]

Given this minimal Ansible play running against Debian Buster

- hosts: test
  become: yes
  roles:
    - igor_nikiforov.docker
  vars:
    docker_version: 5:20.10.11~3-0~debian-buster

The Ansible run fails for the task installing the bash completion

TASK [igor_nikiforov.docker : Install Docker bash completion.] *****************
fatal: [test]: FAILED! => {"changed": false, "dest": "/etc/bash_completion.d/docker", "elapsed": 0, "msg": "Request failed", "response": "HTTP Error 404: Not Found", "status_code": 404, "url": "https://raw.githubusercontent.com/docker/cli/v5:20.10.11~3-0~debian-buster/contrib/completion/bash/docker"}

Looks like version strings on Debian and on the Github Docker CLI repository are no longer compatible.

@frzb, thanks for report, I'll fix it asap.

In the PR above, I applied a regex_replace in the docker_version variable, to use only the tag in the bash-completion installation. Since the correct value for docker_version, based on the versions listed in apt, would be docker_version: "5:20.10.17~3-0~ubuntu-focal"
