Refactor date handling in grab_contest_names function for improved mapping

- Updated the date processing in the grab_contest_names function to sort dates in descending order before formatting, enhancing the accuracy of contest date mapping.
- Adjusted the contest_date_map to replace hyphens with empty strings, ensuring a consistent format for date representation.
- These changes contribute to ongoing efforts to improve data processing and maintain data integrity within the application.
