Powershell deployment script no longer works for new Azure CLI

[BrandoPeter]

Azure CLI forces an update to the latest version, 2.45.0, when running any commands.

For azure ad app create or update, these options have been changed:
--available-to-other-tenants --oauth2-allow-implicit-flow

As per https://learn.microsoft.com/en-us/cli/azure/ad/app?view=azure-cli-latest#az-ad-app-create-optional-parameters, this should now be:
--sign-in-audience --enable-id-token-issuance

--reply-urls has also been changed.
