Get IntuneScopeTagInventory

<#
.SYNOPSIS
    Audits the usage of Scope Tags across Intune objects.

.DESCRIPTION
    Scope Tags are critical for RBAC (Role Based Access Control).
    This script retrieves all Scope Tags and then lists which Device Configs, Compliance Policies, 
    and Scripts are tagged with them.
    
    Helps ensure that restrictions are correctly applied to objects.
