fix: correct API endpoint path from /api/library/scan-settings to /api/libraries/scan-settings

- Update endpoint path in Get Scan Settings Bruno collection file
- Update endpoint path in Update Scan Settings Bruno collection file
- Update endpoint path in API reference documentation

This corrects a typo in the API path where 'library' was singular instead of plural.
