[Enhancement] added Dockerfile, docker-compose.yaml and the README.md

[ShahriyarR]

In the third section of the Youtube video course -> Install and Setup you have used the virtualenv and also changing or upgrading the Python version globally in Linux environments is a dangerous action as the Python version must not be upgraded or touched manually, instead it should be as part of the system upgrade. I think the best is to use Docker here and use the latest version of Python without interfering with the system. This PR basically consists of Dockerfile, docker-compose.yaml, and the README.md file which should ideally explain the usage of docker-compose.
