chore: Use federated auth in CI (#4340)

Move away from a long lived client secret for auth during CI testing
in favor of federated credentials via a service connection.

(To unblock the builds I am seeing how far we can get with our old
trick of delegating stuff to `az` before we teach `azd` how to use
`AzurePipelinesCredential`.)
