Notifications Change

**Describe the bug**
After the latest update, our attempt to have claude only post one notification email instead of one per comment broke

**To Reproduce**

It used to just produce one email with all comments, same as if you manually did a "start a review" in github and added a bunch of comments. After the last update we are getting 1 email per comment.

**Expected behavior**
I expect claude to produce one email with all comments in it instead of an email per comment
