Update Challenge 6 solution template doc comment to mention breaking hyphenated words

[DavidCao22]

CodeRabbitAI specifically requested this change before giving approval.

Breaking hyphenated words is already part of the test suite. We should update the doc comment so that future submissions don't need extra code unrelated to their actual submission to make CodeRabbit happy.

Poem

A little rabbit hopped by the page,
Nibbling hyphens, line by line,
Split the words and set the stage,
Then counted softly, neat and fine.
