Need to wait for a version of org.springframework.kafka:spring-kafka-test that supports kafka 2.8.0

This line is causing an issue seen in tests: https://github.com/spring-projects/spring-kafka/blob/main/build.gradle#L62

[cwperks]

Closing this for now until a new version of org.springframework.kafka:spring-kafka-test is published.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
