Summary

Added new section 'Finding your Lambda extension version number' with step-by-step instructions for locating the AWS FIS Lambda extension version through the Lambda console.

Security assessment

This change adds procedural documentation for finding extension version numbers, which could be useful for troubleshooting or ensuring proper configuration, but there's no evidence of addressing a specific security vulnerability. The change appears to be routine documentation enhancement for user guidance.
