…ed procedure

Problem:
The BigQuery documentation (https://cloud.google.com/bigquery/docs/procedures) needs a standalone, tested Python code sample demonstrating how to call a SQL stored procedure (region tag bigquery_call_procedure).

Solution:

• Add call_procedure(project_id: str, dataset_id: str, procedure_id: str) -> None in bigquery/stored_procedures/bigquery_call_procedure.py (Invoke a BigQuery SQL stored procedure with input parameters and capture its output variable using CALL.)
• Add unit tests (bigquery/stored_procedures/bigquery_call_procedure_test.py) covering both the success path and API error handling (GoogleAPICallError)

Code Review

This pull request introduces a new Python sample for calling a BigQuery stored procedure with input and output parameters, along with its corresponding unit tests and configuration files. The feedback suggests updating the ignored_versions in noxfile_config.py to ensure that the oldest supported Python version (3.10) is tested while intermediate versions (3.11 and 3.12) are ignored, in accordance with the repository's testing guidelines.
