retrosheet.py returns an error for all functions

The Chadwick Baseball Bureau seems to have reorganized their enhanced retrosheet repo. This means some modifications need to be made to retrosheet.py.

Here are the errors for each function:

events('2023')
  File "...\pybaseball\retrosheet.py", line 130, in events
    subtree = repo.get_git_tree(subtree.sha)
                                ^^^^^^^
UnboundLocalError: cannot access local variable 'subtree' where it is not associated with a value

rosters('2023')
  File "...\pybaseball\retrosheet.py", line 164, in rosters
    rosters = [t.path for t in repo.get_git_tree(subtree.sha).tree if str(season) in t.path]
                                                 ^^^^^^^
UnboundLocalError: cannot access local variable 'subtree' where it is not associated with a value

park_codes()
  File "...\pybaseball\retrosheet.py", line 213, in park_codes
    data.columns = parkcode_columns
    ^^^^^^^^^^^^
TypeError: park_codes() takes 0 positional arguments but 1 was given

schedules('2023'
  File "...\pybaseball\retrosheet.py", line 224, in schedules
    schedules = [f.path[f.path.rfind('/')+1:] for f in repo.get_contents('schedule')]
                                                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

season_game_logs('2023')
  File "...\pybaseball\retrosheet.py", line 246, in season_game_logs
    raise ValueError(f'Season game logs not available for {season}')
ValueError: Season game logs not available for 2023

world_series_logs(), all_star_game_logs(), wild_card_logs(), division_series_logs(), division_series_logs(), and lcs_logs() all do not have any output in the terminal and no files are created.

All retrosheet functions should work now
