Replace downloaded Selenium server with Docker container
Instead of downloading the Selenium server and requiring a specific Firefox version to be installed in the system now the Selenium server is run using one of the official Selenium Docker images, which provides both the Selenium server and the appropriate version of Firefox. Moreover, as it is run inside the Docker container, the web browser is now run in headless mode; however, if needed, it can still be viewed through VNC.
