Update CoreAz.ps1 to use the latest Resolve-AzError

[arkoppan]

The script is using Resolve-Error old commandlet from 12.4.0 but this commandlet is deprecated in newer Azure Powershell versions and is failing for Self-hosted agents with newer version of Azure Powershell. So customers are having to downgrade Azure Powershell version to make this task work.
