Updates an existing DataHub dataset's metadata. The description, displayName and logoName fields can be updated.
Only the fields present in the request body are changed; an omitted field keeps its stored value, and an empty string clears it.
The dataset name is immutable and serves as the resource identifier and the ingest provider value. To change how a dataset is displayed in the console and in report results, set displayName; saved reports, budgets, alerts and filters keep working because they reference name.
If name is included in the request body, it must match the dataset name in the URL path. A mismatched name will be rejected with a 400 error.
