Subject: [PATCH] Refactor vocabulary extraction logic in VocabLessonView for
 multiple choice and gap fill exercises

- Enhanced the handling of multiple choice questions by extracting options and determining the correct answer index, improving accuracy in vocabulary mapping.
- Updated the question analysis to support different patterns for extracting German and Bisaya words, enhancing the learning experience.
- Improved gap fill answer extraction by iterating through possible answers and creating unique keys for vocabulary mapping, ensuring better context handling.
- Added detailed error logging to assist in debugging vocabulary extraction issues.
