Add SQL playgrounds, Deep-ML problem set, and OpenCV University courses (#12421)

* add: new machine learning books (MLSys Book, Patterns, Predictions, and Actions)

* add: OpenCV University free courses (PyTorch, TensorFlow, Python, OpenCV)

* add: new SQL practice and editor resources

* add: Deep-ML problem set for competitive programming

* fix: lint issues (pdf tag, ordering, trailing slash)

* fix: correct alphabetical order for SQL resources
