AWS lambda documentation change
Summary
Updated example log entries with corrected dates (2023 to 2025), modified Powertools documentation URLs, and adjusted Billed Duration values in sample logs.
Security assessment
The changes appear to be routine documentation updates (date corrections, URL redirects to AWS domains, and example metric adjustments). No security vulnerabilities, patches, or security feature enhancements are mentioned. The log4j/JndiLookup reference remains unchanged and is part of standard logging examples.
