### Description
<!-- Describe your changes. -->

Remove AzurePowerShell pwsh parameter in
tools/ci_build/github/azure-pipelines/templates/publish-symbolrequestprod-api.yml
so it will default to powershell.exe instead of pwsh.exe.

Some Windows build agents don't have pwsh.exe.

### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
