smoke-test-rank-eval-with-mustache doesn't work with zip distribution

[nik9000]

In #30591 I'm adding support for running qa tests with the distribution configured using -Dtests.distribution. Most of the tests work except smoke-test-rank-eval-with-mustache fails because it tries to form a cluster with an ESIntegTestCase. I'm not 100% sure what the test is testing so I didn't want to change it. But I think it should be changed to work with the zip distribution.

You can reproduce the failure by removing this from qa/smoke-test-rank-eval-with-mustache/build.gradle:

/*
 * One of the integration tests doesn't work with the zip distribution
 * and will be fixed later.
 * Tracked by https://github.com/elastic/elasticsearch/issues/30628
 */
if ("zip".equals(integTestCluster.distribution)) {
    integTestRunner.enabled = false
}

And then running:

./gradlew -p qa/smoke-test-rank-eval-with-mustache/ -Dtests.distribution=zip check
