AWS code-library documentation change
Summary
Removed 'Get started' section containing Java and Python code examples for describing Neptune DB clusters
Security assessment
The change removes general code examples for Neptune cluster description operations. There's no evidence of security vulnerability fixes, security weaknesses, or incident response. The removed content was routine SDK usage documentation without security-specific context.
