Update Entity Analyzer: intelligent user identifier detection

[Yaniv-Shasha]

Proposed Changes

This PR updates the Incident-Trigger-Entity-Analyzer playbook (azuredeploy.json) with the following improvements:

What Changed

Area	Change
description	Extended: includes "intelligent user identifier detection supporting objectGuid, aadUserId, UPN, and Name+UPNSuffix"
lastUpdateTime	Updated to 2026-02-10
author.name	Fixed casing to Yaniv Shasha
Logic App tags	Added hidden-SentinelTemplateName and hidden-SentinelTemplateVersion: 2.0
User loop logic	Added Condition_-_Check_Valid_User_Identifier with coalesce() across objectGuid, aadUserId, UPN (both casings), and Name+UPNSuffix
Else branch	Added Add_Skip_comment_to_incident when no valid user identifier exists
API ID casing	Standardized to azuresentinel (lowercase)
Comment HTML	Cleaner formatting

Why

Previously the playbook only used AadUserId to identify users. Many Sentinel incidents provide user entities with different identifier types (objectGuid, UPN, Name+UPNSuffix), causing silent failures. This update ensures robust user resolution across all common identifier formats.
