fix(ci): pin bq table creation to EU location

BigQuery was intermittently failing with "not found in location EU"
because bq query without --location can default to US, while the
kestra_unit_test dataset lives in EU. Soda's BigQuery client routes
queries to the dataset's region (EU), causing a location mismatch.
