How do I populate the owner column in the generated docs?

Due to the nature of the field, you won't be able to change the owner column in your generated documentation.

The owner field in dbt-docs is pulled from database metadata (catalog.json), meaning the owner of that table in the database. With the exception of exposures, it's not pulled from an owner field set within dbt.

Generally, dbt's database user owns the tables created in the database. Source tables are usually owned by the service responsible for ingesting/loading them.

If you set meta.owner, you should now be seeing that field appear under meta (pulled from dbt), but still not under the top-level owner field.
