…uilt-in system procedure

Problem:
The BigQuery documentation (https://cloud.google.com/bigquery/docs/procedures#call_a_system_procedure) needs a standalone, tested Python code sample demonstrating how to call a built-in system procedure (region tag bigquery_call_system_procedure).

Solution:

• Add call_system_procedure(project_id: str, dataset_id: str, materialized_view_id: str) -> None in bigquery/stored_procedures/bigquery_call_system_procedure.py (Invoke a built-in BigQuery system procedure such as BQ.REFRESH_MATERIALIZED_VIEW using CALL.)
• Add unit tests (bigquery/stored_procedures/bigquery_call_system_procedure_test.py) covering both the success path and API error handling (GoogleAPICallError)

Code Review

This pull request adds a new Python sample and tests for calling the BQ.REFRESH_MATERIALIZED_VIEW system procedure in BigQuery. The feedback recommends updating the ignored_versions in noxfile_config.py to ensure only the oldest and newest supported Python versions (3.10 and 3.13) are tested, ignoring intermediate versions.

[gemini-code-assist]

According to the repository guidelines, we should only test the oldest and newest supported Python releases in test configurations, ignoring intermediate versions. Since the oldest supported version is Python 3.10 (as specified in requirements-test.txt) and the newest is Python 3.13, we should test 3.10 and 3.13, while ignoring the intermediate versions 3.11 and 3.12.
