[Ingest FHIR to BigQuery]

[akirakakar]

During the clean-up session in step 6, the following code is asked to run

bq rm -r -f $PROJECT_ID:$DATASET_ID

But I think it should be the following instead

bq rm -r -f $PROJECT_ID:$BQ_DATASET

I have tested on my end and works correctly with the correct command.
