I don't understand this PR.

I wish the other version tests would run on the nightly build, but I don't know how to conduct the tests.

@yurishkuro I apologize for the confusion. I am new to writing pipeline scripts, so could you please provide me with more context? thanks 😊

This is not solving any useful problem. We do want all e2e tests to run on PRs. But we don't want to run tests against Kafka v2 because it's EOL.

If you don't understand the problem described in the ticket, the best course is to ask clarifying questions, not trying to implement random changes and asking "is this it?"
