Refactor main.go to require only Spotify URL

Streamline the user input process to require only Spotify URLs instead of a track name or URL. Removed the flexibility of inputting a track name as it leads to confusion and uncertainty about the input format. This change simplifies the user interaction with the application and it ensures that the correct format (Spotify URL) is always used, reducing the chance of error. Error messages and usage template are also updated accordingly to reflect this change.
