如何将Stream<Person>分组到Stream<List<Person>>中，而不是分组到Map<String、<List<Person>>中？

import java.util.*;
import java.util.stream.Collectors;
import java.util.stream.Stream;

public class PersonGroupingExample {

    public static void main(String[] args) {
        List<Person> people = Arrays.asList(
                new Person("Alice"),
                new Person("Bob"),
                new Person("Alice"),
                new Person("Charlie")
        );

        // 先执行分组操作
        Map<String, List<Person>> groupedByNames = people.stream()
                .collect(Collectors.groupingBy(Person::getName));

        // 将Map的值转换为一个Stream<List<Person>>
        Stream<List<Person>> groupedStream = groupedByNames.values().stream();

        // 打印结果
        groupedStream.forEach(System.out::println);
    }

    static class Person {
        private String name;

        public Person(String name) {
            this.name = name;
        }

        public String getName() {
            return name;
        }

        @Override
        public String toString() {
            return "Person{" +
                    "name='" + name + '\'' +
                    '}';
        }
    }
}

Stream<List<Person>> personListsStream = Stream.of(people).map(list -> new ArrayList<>(list));
