resolved the problem with main.py

[erenyeager101]

The issue in main.py is due to calling main() recursively inside the replay_game() function, which will cause a stack overflow and incorrect game logic.

To solve this, instead of calling main() again, reset the game variables within the same game loop so that it restarts cleanly.

Changes that i made:
Replay Logic: Added a reset_game() function that resets all the game variables, making the game restart smoothly when the "Replay" button is pressed.
Removed Recursive Call: The replay_game() function now only resets the game state instead of calling main() again, preventing recursive function calls.
Global Variables: Some variables like cells, fill_count, and players are now global so they can be reset properly when replaying the game.
