Add tests for Docker

[Hritik14]

We're shipping Docker containers which differ with our current test environment (for eg, test environment runs on ubuntu-latest but the Docker container runs on PYTHON image which is based on Debian).
Due to divergence like these, we need to have separate tests for Dockerfile.
