Need to check for runtime and runtime version when publishing a function app

Need to check for runtime and runtime version when publishing a function app

Scenario:
Locally, I create a PowerShell function app targeting PowerShell 7. When publishing the the app, check runtime and runtime version to make sure the settings get propagated to the cloud.

Start in the repository's publish command flow and trace how a locally created PowerShell 7 function app is packaged and sent to Azure. Verify where runtime and runtime-version settings are read and propagated, then confirm publishing preserves those settings in the cloud for the described scenario.
