Natural sorting is needed for sort_by_label_natural() and sort_by_label_natural_desc() functions in MetricsQL - see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6192 and https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6256 Natural sorting will be also used by `| sort ...` pipe in VictoriaLogs - see https://docs.victoriametrics.com/victorialogs/logsql/#sort-pipe
