Improve red letter edition to highlight only Christ's spoken words

Updated the red letter functionality to wrap only the specific words
Jesus spoke within each verse, rather than entire verses. This provides
more accurate red letter highlighting similar to traditional red letter Bibles.

Changes:
- Modified red_letter.py to search for and wrap only Christ's words
- Updated JSON structure to store actual quoted text
- Changed filter to handle both full verses and partial quotes
- Improved accuracy of red letter highlighting
