KAFKA-18574 Sort test tables in JUnit summary by class and test name (#23945)

The test tables in the JUnit job summary (Failed, Flaky, Skipped,
Quarantined and New) are printed in the order the reports are parsed,
which follows the filesystem order of `glob()` and is not stable across
environments. This sorts each table by class name and test name before
rendering.

This is a continuation of #21786, which was closed as stale.
