Summary

Added PowerShell V5 examples for DescribeSecurityGroups API with VPC/EC2-Classic differentiation and filtering examples

Security assessment

While security groups are fundamental security controls, these changes only provide usage examples for existing API operations. The documentation clarifies VPC vs Classic usage but doesn't indicate any security vulnerability fixes or new security capabilities.
