fix: Remove remaining cold_storage_after validation blocks from rules variable

Remove problematic validation logic for cold_storage_after fields in the rules variable that was causing CI failures for organization_backup_policy and other examples. These validation blocks had the same null handling issues as the plans variable.

This resolves the failing "Validate Examples (organization_backup_policy)" CI check and ensures all examples can properly handle optional cold_storage_after fields.
