Summary

Added regional availability notes for expanded filterable fields and RDS Protection limitations in AWS Dedicated Local Zones

Security assessment

This change documents regional limitations for GuardDuty features - specifically that expanded filterable fields are only available in the AWS partition and RDS Protection is not supported in AWS Dedicated Local Zones. This is feature availability documentation that helps users understand deployment constraints but doesn't address any security vulnerability.
