Add drop-off interaction with cooking equipment

The code now includes a new hook called 'drop_off_on_cooking_equipment'. This hook is used to track and score instances of players dropping off items on the cooking equipment in the Overcooked game simulator. This enhancement will allow for more detailed game simulations and scoring capabilities.
