Update script.js

This script identifies duplicate tickets or tasks in ServiceNow where the number field is not unique. Normally, ServiceNow enforces unique ticket numbers, but misconfiguration at the dictionary level can lead to duplicates.

The solution uses GlideAggregate to:
-Group records by number and count occurrences.
-Filter duplicates where the same number appears more than once.
