feat(bigquery): Implement getArray in BigQueryResultImpl (#3693)
* Implement getArray in BigQueryResultImpl * deps: update dependency com.google.apis:google-api-services-bigquery to v2-rev20250216-2.0.0 (#3688) * build(deps): update dependency org.apache.maven.plugins:maven-compiler-plugin to v3.14.0 (#3689) * deps: update ossf/scorecard-action action to v2.4.1 (#3690) * deps: update actions/upload-artifact action to v4.6.1 (#3691) * Remove public from BigQueryResultSet class def * Remove INTEGER_ARRAY_FIELD_LIST from IT test file * Add ReadApi IT test * Try old IT test values * Convert Time objects to strings for comparison * Fix Formatting --------- Co-authored-by: Mend Renovate <[email protected]>
