Fix verse commentary validator to allow apostrophes and verse ranges

Updated the VerseCommentary validation regex pattern to support:
- Apostrophes in book names (e.g., "Solomon's Song")
- Verse ranges (e.g., "Genesis 1:4-5")

This brings the validator in line with other validators in the codebase
and fixes failing data validation tests.
