AWS greengrass documentation change

Service: greengrass · 2025-08-22 · Documentation low

File: greengrass/v2/developerguide/device-auth.md

Summary

Updated all IoT Core ARNs in policy examples to include specific region (us-east-1) and account ID (123456789012)

Security assessment

Changes standardize examples with concrete values but don't address security vulnerabilities or add security documentation. Proper ARN formatting improves policy accuracy but doesn't change security posture.
