Refactor API tags in swagger.yaml to use shortened prefixes

- Updated tags from 'network_data' to 'ne_data' for consistency and brevity.
- Changed 'network_element' to 'ne' across various endpoints for improved readability.
- Adjusted related descriptions in the tags section to reflect the new naming conventions.
