Refactor argument parser in Overcooked Simulator

The argument parser and related function calls have been moved from the `__main__` function in the Overcooked Simulator to the `main` function. This change streamlines the function calls and improves code readability and management. Furthermore, it ensures that essential configurations are in place before the game server and GUI are initiated.
