This corrects the index version filter in the migration reindex logic. We want to require reindexing of indices if they were created before the current version, because those indices will not be writable in the next version. So for Elasticsearch 9, we want to return any indices created before Elasticsearch 9 because those will not be writable in Elasticsearch 10.
