fix: Signature of "insert_rows" incompatible with supertype "DbApiHook"

[rawwar]

This PR fixes the following mypy check failure for the google provider.

airflow/providers/google/cloud/hooks/bigquery.py:228: error: Signature of
"insert_rows" incompatible with supertype "DbApiHook"  [override]
        def insert_rows(

in DbApiHook--> insert_rows method was recently updated to include executemany parameter. But, Google provider --> BigQueryHook inherits the DbApiHook. Is it necessary that insert_rows (link to the def) defined in an inherited class to have same signature? I've been seeing the following error locally and am wondering if BigQueryHook also needs to include the newly added executemany parameter
