Resolve "Hook when putting items back on dispenser"

Closes #111

See merge request scs/cocosy/overcooked-simulator!84

Positions and state of items and counters in the cooperative_cuisine/pygame_2d_vis/sample_state.json file were edited. This included adding new counters and items, changing current nearest counter information and positioning, modifying held objects, and altering active effect conditions among others. The changes cater for a better test coverage.

- added number of players to level info
- added draw cook method to vis
- Draw cook and meal on sufaces and show them on postgame screen instead of text

The reference to the config dictionary has been refactored for better organization in the drawing.py file. Previously, key-value pairs were directly accessed from the config dictionary, now they are accessed from a nested dictionary under the "Gui" key. This change aims to improve code clarity and manageability.

Resolve "Put drawing constants in vis config"

Closes #117

See merge request scs/cocosy/overcooked-simulator!83

The visualization settings for the pygame 2d visualization such as 'use_player_cook_sprites', 'show_interaction_range', and 'show_counter_centers' are now part of the configuration in 'visualization.yaml'. If these settings are not defined in the configuration, the program will use default values. This change allows for easier modification of the visualization aspects without directly changing the code each time.

- Language can be selected from visualization.yaml, "en" and "de" for now.

This commit introduces numerous changes outlined in the CHANGELOG. Major updates include sending full websocket url in player_info and achieving ">90"% code coverage in tests. Several modifications were also made such as refactoring extra_setup_functions, allowing study config overwriting environment config attributes, and changing time comparisons convention. Player config in the environment class has also been refactored to a dataclass.
