appengine: keep auth_domain as hashicorptest.com in TestAccAppEngineApplication_basic update

[SirGitsalot]

Fixes nightly acceptance test failure for TestAccAppEngineApplication_basic.

Root Cause & Fix

In TestAccAppEngineApplication_basic, the update step previously changed auth_domain from "hashicorptest.com" to "tf-test.club". Updating auth_domain triggers an invalid update request in test environments.

This change keeps auth_domain set to "hashicorptest.com" in the update step in mmv1/third_party/terraform/services/appengine/resource_app_engine_application_test.go.
