Subject: [PATCH] KAFKA-19050: Exclude empty streams integration artifact

Keep the test artifacts published while removing the empty main JAR from the streams integration tests publication. Disable Gradle module metadata for this test-only publication because it cannot represent the component after the main artifact is removed.
