Refactor function names and improve data fetching

Renamed two functions in openai.py and optimized the data fetching in table_schema.py. Also updated an example script to reflect these changes. The renaming of methods make_mindsdb_tool to make_query_tool and litellm_text2sql_callback_tool to make_data_tool is done for clarity. The simplification of data fetching process by removing redundant steps enhances efficiency. Changes in the example script are made to adhere to these modifications.
