Notes: Update reaction E2E tests to renamed fixture and method

Trunk's collab-sidebar refactor renamed the test fixture and helper:
- blockCommentUtils → blockNoteUtils
- addBlockWithComment → addBlockWithNote

Update the Emoji Reactions describe block to use the current names so
Playwright stops failing with 'Test has unknown parameter blockCommentUtils'.
