Add reliable check for Kafka broker being ready

[shashank-iitbhu]

Which problem is this PR solving?

Resolves #5148

Description of the changes

• The previous approach used nc to check the availability of the Kafka port, which was not reliable, especially when the Kafka container was started asynchronously. The updated script now ensures a more reliable check for Kafka readiness by attempting to list topics using kafka-topics.sh within a loop. This modification ensures that the script waits until Kafka is fully initialized before proceeding with integration tests.

How was this change tested?

• This modification ensures that the script waits until Kafka is fully initialized before proceeding with integration tests.
• Ran bash scripts/kafka-integration-test.sh -k from the project root.
