[bugfix] Init BrokerQueryEventListener

[tibrewalpratik17]

During testing of release-1.2, we discovered that our broker query event listener framework was not functioning as expected. When initializing the BrokerQueryEventListener, we call the init method with configurations needed for pushing messages to Kafka and M3. However, after the release, we stopped receiving messages in both systems.

It appears that during the refactoring in #13179, we missed the call to _brokerQueryEventListener.init(config); after creating the listener instance. This PR reintroduces that missing call.
