New-WinGetSource fails if resource group region doesn't support classic App Insights

Brief description of your issue

Classic mode for Application Insights will be deprecated in 2024, and there's several regions that don't support it. If the created resource group is in one of those regions, the New-WinGetSource cmdlet will fail with an error like this:

Line |
 157 |          New-ARMObjects -ARMObjects $ARMObjects -RestSourcePath $RestS …
     |          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | Failed to create Azure object. 13:28:01 - The deployment 'applicationinsights' failed with error(s). Showing 1 out of 1 error(s). Status Message: Region doesn't support Classic resource mode for Application Insights
     | resources. Please use Workspace-based mode. (Code:BadRequest)  CorrelationId: daf01282-078d-4ee0-b24e-84782f2ccda5
