feat: Create and populate a 2D dynamic ArrayList (3x3) using user input

🧠 Logic:
- Initializes a 2D `ArrayList<ArrayList<Integer>>` with 3 inner lists.
- Uses nested loops to input 3 elements into each of the 3 inner lists.
- Displays the 2D list structure as a single output.

🔍 Demonstrates dynamic 2D list creation where row sizes and content can be varied.
