fix: ready condition in ClickHouse (#441)

The ClickHouse dockerfile exposes several ports (8123, 9000, etc.). If
no port is specified in the `ready_conditions` the first exposed one is
chosen, which is non-deterministic. This means Clickhouse would fail to
start (from the testcontainer's point of view).

This PR explicitly adds the good port to the `ready_conditions` to fix
that.
