Create Auto_Tag_Incident.js

Incident Auto-Tagging
Automatically detects keywords like email, VPN, or server from the incident’s short description and description.
Creates a corresponding Label (if not already present) and a Label Entry linked to that incident to fulfill the requirement of auto tagging.

Benefit:
Helps automatically tag incidents with relevant keywords, improving searchability, categorization, and visibility across the platform.

Type: Before Business Rule
Table: Incident [incident]

+    // from the Incident’s short description and description fields.
+    //
+    // Based on detected keywords:
+    //  - A corresponding Label is created (if not already present)
+    //  - A related Label Entry is created for that Incident
+    //
+    // 💡 Benefit:
+    // Adding Labels and Label Entries helps automatically tag
+    // incidents with the right keywords — improving searchability,
+    // categorization, and visibility across the platform.
