Get-AzExemption.ps1 doesn't output any exemptions

Describe the bug I'm running the script against our pacEnvironment with a few exemptions, the output files contain an empty JSON array of exemptions:

{
  "$schema": "https://raw.githubusercontent.com/Azure/enterprise-azure-policy-as-code/main/Schemas/policy-exemption-schema.json",
  "exemptions": []
}

To Reproduce

I'm running: Get-AzExemptions -pacEnvironment "production" against an existing pacEnvironment

I have verified that the script manages to retrieve all exemptions within the scope, the issue seems to be with the Helper function Output-PolicyExemptions

Expected behavior

My expectation is that the script will output a all exemptions in the scope of the pacEnvironment
