Update hitting.py to fix unexpected keyword errors

[sharmaakhil100]

Why

Running this code with 'gameLog', which is a valid stat input was giving an unexpected keyword summary exception:

    stats = ['gameLog']
    groups = ['hitting']
    params = {'season': 2024}
    all_game_stats = mlb.get_player_stats(664034, stats, groups, **params)

What

Changes were made to ignore unexpected keywords instead of throwing an error

Tests

Tested with original library code calls and now it is working
