📝 Walkthrough

Walkthrough

This change updates a documentation reference in the Kafka event pipeline tutorial. The "Full Source Code" section previously pointed to an invalid GitHub repository path. The update corrects this reference to direct readers to the valid sample code location at wso2/integration-samples/integrator-mi-profile/KafkaConsumerAndProducer. This resolves the issue where users were unable to locate the referenced sample code.

Why listing MI sample here? Shouldn't it be Ballerina/Default profile sample?
