[pr-66] fix: make old_line and new_line optional for image diff discussions

🐛 Bug Fix:
- Image files in GitLab MR discussions use x/y coordinates instead of line numbers
- Fixed schema validation error when fetching discussions on image files

📝 Details:
- Changed old_line and new_line from required to optional in GitLabDiscussionNoteSchema
- Allows proper handling of image diff comments that use position_type: 'image'
