Leave pull request numbers out of patch notes

[Drefvelin]

Summary

• GitHub squash titles like (#33) are removed before a patch note is stored.
• Notes already saved still hide that number when the week is shown to staff or players.

Test plan

• python3 -m unittest backend/src/patchnotes/test_summarize.py backend/src/api/test_patchnotes_routes.py
• A line stored as Added evil RP sessions (#33) is returned as Added evil RP sessions.

Made with Cursor

Summary by CodeRabbit

• Improvements
