Bug 24875: Remove extra punctuation from tools start page

The patron clubs note was ending with .., but patch also removed
some single . to be consistent with the majority of entries on the
tools page.

To test:
- Check the tools start page for ending . in the notes
- Apply patch
- Verify the punctuation is now consistent
