Hey @ishyesh this is actually covered here in the 'addding new drivers' page but I think it could be made clearer. How do you feel about updating the "common" instructions here instead?: https://superset.apache.org/docs/databases/docker-add-drivers

.. And then link to it from the Clickhouse page? Adding database drivers when using Docker Compose is the same for any database after all 🤔
