[Cloud Security] remove nvd link generation logic from Kibana (#165330)

## Summary

- fixes: elastic/security-team#7490

The NVD generation logic will be happening on the `cloudbeat` side after
elastic/cloudbeat#869 (comment) is done and
elastic/cloudbeat#1303 is merged, so we can
remove the logic from Kibana and use what's in `vulnerability.reference`
