feat: improve error handling for getting the latest downloaded TCX file

Improve the error handling in the get_latest_download() function to handle the case when no TCX file is found in the Downloads folder. Instead of raising a FileNotFoundError, the function now prompts the user to manually provide the file path. If an error occurs while getting the file path, a ValueError is raised.

This commit addresses the issue of the program crashing when no TCX file is found, providing a more user-friendly experience.
