Steward in Tags vs object Steward?

How does the "Steward" tag from [M8-3](https://github.com/GoogleCloudPlatform/dataplex-labs/blob/main/dataplex-quickstart-labs/02-lab-guide/module-08-3-create-tag-template-for-catalog-entry.md#12-associate-the-tag-template-to-the-custom-catalog-entry) relate to the steward assignment in [M8-2](https://github.com/GoogleCloudPlatform/dataplex-labs/blob/main/dataplex-quickstart-labs/02-lab-guide/module-08-2-create-custom-entry-in-catalog.md#4-add-a-data-steward-for-the-custom-catalog-entry)?

Read the M8-2 section “Add a data steward for the custom catalog entry” and the M8-3 section “Associate the tag template to the custom catalog entry,” following the linked anchors. Clarify how the Steward tag relates to the steward assignment, and update the lab guidance so the distinction or relationship is explicit.
