[FEATURE] Connect-PnPOnline is not working for national cloud Bleu

[Trista-lover]

Expected behavior

I want to trigger requests using app-only in new National Cloud environment 'Bleu' which is for France, so I need to create a Entra ID APP and connect it by Connect-PnPOnline, expect it connect successfully.

Actual behavior

It failed to create Entra ID APP in Bleu environment by Register-PnPAzureADApp, and then I manually create it in Azure portal, but I still cannot connect it by Connect-PnPOnline with "Confidential Client is not supported in Cross Cloud request." error.
