AWS code-library documentation change

Summary

Added Swift SDK examples for DescribeSecurityGroups API with pagination and direct query implementations

Security assessment

Provides documentation for security group enumeration features but doesn't fix vulnerabilities. While security group configuration is security-critical, the change only adds API usage examples without addressing specific security weaknesses.
