Auto-discovery disabled for misc zone

In module 6 chapter [1.4.2](https://github.com/GoogleCloudPlatform/dataplex-labs/blob/main/dataplex-quickstart-labs/02-lab-guide/module-06-discovery.md#142-review-entities-automatically-createdd) we cannot find any entities because the zone was created without auto-discovery.

Start with module-06-discovery.md, especially section 1.4.2, and inspect how the misc zone is created before that step. Verify whether auto-discovery is enabled for the zone; the lab is done when entities appear as described in the section.
