Subject: [PATCH] Fix: Use plural resource names in createNote URL construction

- Changed  to s to use the correct plural form in API endpoints

- This fixes 404 errors when trying to add notes to issues or merge requests

- Added a test file to verify the fix

- Conforms to GitLab API documentation which uses plural resource names (issues, merge_requests)
