Fix: Pass along kwargs when creating a sql agent (#2350)

Currently, `agent_toolkits.sql.create_sql_agent()` passes kwargs to the
`ZeroShotAgent` that it creates but not to `AgentExecutor` that it also
creates. This prevents the caller from providing some useful arguments
like `max_iterations` and `early_stopping_method`

This PR changes `create_sql_agent` so that it passes kwargs to both
constructors.
