Subject: [PATCH] docs: fix incorrect column references in AGG_STATE example

The AGG_STATE example in zh-CN/docs/2.1/table-design/data-model/aggregate.md
was using non-existent columns `k2` and `k3`, which do not match the table schema.

Updated the example queries to use the correct columns `v1` and `v2`:

```sql
insert into aggstate select 3,sum(v1),group_concat_union(v2) from aggstate;

select sum(v1), group_concat_merge(v2) from aggstate;

select sum(v1), group_concat_merge(v2) from aggstate where k1 != 2;

 如果不想要最终的聚合结果，而希望保留中间结果，可以使用 `union` 操作：
 
 ```sql
-insert into aggstate select 3,sum_union(k2),group_concat_union(k3) from aggstate;
+insert into aggstate select 3,sum(v1),group_concat_union(v2) from aggstate;

+select sum(v1), group_concat_merge(v2) from aggstate;

+select sum(v1), group_concat_merge(v2) from aggstate where k1 != 2;

 ```
 
 此时表中计算如下：
