Create TechTrekwithAJ-Automate Discovery using flow Script Step.js

This script is used in ServiceNow to automate device discovery on a network by triggering Quick Discovery using a MID Server. It is typically used within a workflow or flow, where you want to scan a device using its IP address.

It adds reliability by using two MID servers, so if one fails, the other is used as a backup.
