BigQuery - Allow jagged rows

[moseleyi]

Describe the bug

When loading data from GCS, I would like to use other options like described here: https://cloud.google.com/bigquery/docs/loading-data-cloud-storage-csv
One of them is ``--allow-jagged_rows`

However adding this to yml produces an error:

Encountered an error while running operation: Database Error
  Option allow_jagged_rows value has type INT64 which cannot be coerced to expected type BOOL at 

Steps to reproduce

Add following options to a GCS external table:

options:
  format: csv
  skip_leading_rows: 1
  allow_jagged_rows: true

Expected results

The external table to be created

Actual results

Error
