Missing documentation when creating a Config with Refresh Mode set to Auto

[HarukaIzumisawa]

I would like to create a Config with Refresh Mode set to Auto to achieve scheduled tag updates. However, there is no detailed explanation in the ui_guide.md. I think I need to request the scheduled_auto_updates function after creating the Config in order to perform scheduled updates. The source code states that this method is requested by Cloud Scheduler, but the documentation does not describe the procedure for creating this Cloud Scheduler job. https://github.com/GoogleCloudPlatform/datacatalog-tag-engine/blob/b64520a4780e66e72215efd5cf530e3f87b61059/main.py#L3040-L3044 Therefore, we propose the following

Proposal:

• Add documentation on the behavior of Refresh Mode when set to Auto.
• Add documentation on how to create and configure a Cloud Scheduler job.
