Implement Game Over on Snake Biting Itself

[ANKITy102]

Description:

Currently, the game only ends when the snake collides with the boundaries. However, to enhance gameplay realism and challenge, update the game logic to trigger a game over when the snake bites itself.

Tasks:

• Update game logic to detect when the snake bites itself.
• Implement functionality to end the game when the snake bites itself.
• Ensure that the game over condition on self-biting provides appropriate feedback to the player.

Resolution:

Solve the tasks outlined above and submit a pull request referencing this issue ID (#ISSUE_ID) with a screenshot or video demonstrating the implemented feature.
