Use keyword arguments in `python-sqlite3` test
/tmp/test-dir/python-sqlite3/./container.py:5: DeprecationWarning: Passing more than 1 positional argument to sqlite3.connect() is deprecated. Parameters 'timeout', 'detect_types', 'isolation_level', 'check_same_thread', 'factory', 'cached_statements' and 'uri' will become keyword-only parameters in Python 3.15.
Tested successfully on Python 3.13rc1, 3.8, and PyPy's Python 2 implementation, for good measure.
