…d query an Apache Iceberg BigLake table

Problem:
The BigQuery documentation (https://cloud.google.com/bigquery/docs/query-iceberg-data) needs a standalone, tested Python code sample demonstrating how to refresh and query an Apache Iceberg BigLake table (region tag bigquery_query_iceberg_table).

Solution:

• Add query_iceberg_table(project_id: str, dataset_id: str, table_id: str, connection_id: str, metadata_uri: str) -> None in bigquery/biglake/bigquery_query_iceberg_table.py (Update an Apache Iceberg external table definition to point to the latest metadata snapshot on Cloud Storage and query its rows.)
• Add unit tests (bigquery/biglake/bigquery_query_iceberg_table_test.py) covering both the success path and API error handling (GoogleAPICallError)

Code Review

This pull request introduces a new Python sample and associated tests for refreshing and querying Apache Iceberg external tables in BigQuery. The feedback suggests improving the sample's reusability by replacing the specific column selection in the SQL query with a generic SELECT * and a LIMIT clause. Additionally, it recommends updating the test configuration in noxfile_config.py to only test the oldest and newest supported Python versions (3.10 and 3.13) in accordance with testing guidelines.
