TheAlistairRoss Update role requirements for Microsoft Sentinel UEBA prerequisites

[TheAlistairRoss]

The permissions prerequisites for UEBA were incorrect. Having only Log Analytics contributor or Microsoft Sentinel contributor leads to failures when enabling UEBA as the BehaviourAnalyticsInsights OMS solution would not be deployed. Updated the required permissions with tested combinations, highlighting the least privileged permissions.
