Fixed recursion issue by resetting game without restarting the function

[Navaneeth832]

Previously, the game had two issues:

Unnecessary recursion: When a player chose to play again (y option), play_game() was called recursively instead of properly resetting the game, leading to function call stacking and potential memory issues.
Game continuing after pressing 'n' twice: If a player pressed 'n' once, the game sometimes did not exit immediately and continued running.
Attempts not resetting: The number of attempts was not resetting properly when the game restarted.
Changes made:

Replaced play_game() call with start(), ensuring a fresh reset without unnecessary recursion.
Fixed the issue where pressing 'n' twice caused the game to continue unexpectedly.
Ensured that the number of attempts resets correctly when starting a new round.
Impact:

The game now properly resets when a player chooses to play again.
The game exits immediately when 'n' is pressed.
The number of attempts resets correctly for each new game session.
