Added 'generated' to .gitignore, updated pdoc footer text in .gitlab-ci.yml, and included interaction state for player in player.py. The player interaction with the counter is now being tracked and a new comment was added for the progress method. This will enhance player's tracking and usage in the game environment.

This commit simplifies the overcooked environment by refactoring the way counters are created and managed. A new CounterFactory class is introduced, offloading logic from the environment class. In addition, the symbol to character mapping and other environment-related configurations are moved to a separate YAML file. The .gitignore file is also updated to ignore the 'playground' directory. Making these changes enhances code maintainability and readability.
