Create script.js

This Business Rule checks for Change Requests linked to the same Configuration Item (CI) whenever an Incident is created or updated.
If any active CRs are found (excluding Closed and Canceled), their numbers are added to the Incident’s work notes.  
This helps agents identify related changes quickly and avoid duplicate effort.
