Fix createNote function URL construction: use plural resource names and avoid duplicate /api/v4

This fix resolves two issues in the createNote function:

1. Use plural form for resource types (issues, merge_requests) in the URL path

2. Remove duplicate /api/v4 in URL construction, which caused 404 errors

These changes align with the GitLab API documentation and fix 404 errors when adding notes to issues or merge requests.
