refactor: Improve parsing of flight schedule data

The code changes in `schedule_parser.go` enhance the parsing logic for flight schedule data. This improves the accuracy and functionality of the code when extracting information such as index, task, date, flight number, and aircraft registration from the input line. The changes ensure more reliable and consistent parsing of flight schedule data.
