feat(workflows): Add Docker installation step

To facilitate the execution of tests within a controlled environment, Docker is now installed as part of the CI testing workflow. This addition ensures that any Docker-dependent steps, specifically the building and running of an SSH Server Docker container, execute seamlessly. Previously, the assumption was that Docker would be pre-installed on the runner, which could lead to inconsistencies or failures in environments where this was not the case. By explicitly including the Docker installation step, the workflow becomes more portable and resilient across different CI execution environments.
