AWS neptune documentation change
Summary
Added documentation for new Gremlin language steps in DFE engine and removed temporary warning about engine issues
Security assessment
The changes primarily document new query language features (Gremlin steps) and remove a temporary warning about engine stability. While the removed warning previously indicated operational issues, there's no explicit mention of security vulnerabilities being addressed. The additions focus on functionality expansion rather than security controls or vulnerabilities.
