'''
This function, get_leaderboard_df, is designed to read and process evaluation results from a specified results path and requests path, 
ultimately producing a leaderboard in the form of a pandas DataFrame. The process involves several steps, including filtering, sorting, 
and cleaning the data based on specific criteria. Let's break down the function step by step:

'''
