Add 2048 Game to Old-School-Game

Hello @ajaynegi45 👋👋
I would like to propose adding a **2048 game** to the project as a new feature.
This game will enhance user engagement with a fun, logic-based puzzle game inspired by the classic 2048 sliding tile challenge.

The features that I will be implementing are:
✅A fully functional 2048 game with a 4x4 grid.
✅Keyboard controls (arrow keys) and touch support for mobile.
✅Score tracking, animations, and win/lose conditions.
✅Option to restart/reset the game.

Please assign this issue to me😊😊
Thank You!!
