LGTM :)
@VladaZakharova just making sure, are we good with the definition of the min. version of gcloud-aio-bigquery?

Edit: It seems that we need to increase the min. version of gcloud-aio-bigquery to at least 7.1.0, when the location patch was released.

This change was made to remove using event_loop inside the code. Since in Airflow recently was added ability to support async_to_sync without using event_loop, there is no need now here in the bq hook to use this event_loop call at all. So the change was made here not because of the library update, but because in Airflow now it is possible to avoid creation of event_loop every time we need to create sync call.
