Add missing dependency group for async SQLAlchemy tests (#1474)
* Add missing dependency group for async SQLAlchemy tests
FAILED tests/plugins/test_polars_extensions.py::test_polars_database -
ImportError: The SQLAlchemy asyncio module requires that the Python 'greenlet'
library is installed. In order to ensure this dependency is available, use the
'sqlalchemy[asyncio]' install target: 'pip install sqlalchemy[asyncio]'
