AWS aws-backup documentation change

Summary

Added a note clarifying that AWS Backup evaluates cron expressions for restore testing plans only between 00:00 and 23:59, and start times later than 11:59 for 'every 12 hours' plans result in once-daily execution.

Security assessment

This is a functional clarification about cron expression behavior in restore testing plans. There is no mention of security issues, vulnerabilities, or security features; it is purely an operational note.

+AWS Backup evaluates cron expressions between 00:00 and 23:59. If you create a restore testing plan for "every 12 hours" but provide a start time of later than 11:59, it will only run once per day.
