Add support for new tech stacks/projects.

Raise a pr, contributions are welcome!

The issue asks for adding support for new tech stacks/projects but gives no specifics. A newcomer would need to understand what 'Dockerizing-projects' currently supports, decide on a new stack to add, and figure out how to structure a Docker setup for it. Start by examining existing project directories and Dockerfiles in the repository to see the pattern. Then choose a technology, research its typical Docker configuration, and create a new folder with appropriate files. 'Done' means a new, working Dockerized example is added and documented.
