      Update a Security Command Center BigQuery export.

      BigQuery exports that are created with Security Command Center API V2 and
      later include a `location` attribute. If the `location` attribute is
      included in the resource name of a BigQuery export, you must specify it
      when referencing the export. For example, the following BigQuery export
      name has `location=eu`:
      `organizations/123/locations/eu/bigQueryExports/test-bq-export`.
