Mingyu Chen 74a482ca7f [fix] fix docs build bug (#9293 )

After this PR #9272, the `docs/build_help_zip.sh` will run failed.
This PR fix this issue.
But the help module still has some parse problem, I will fix it in next PR.

This CL mainly changes:
1. fix `docs/build_help_zip.sh` error
2. remove `sql-reference-v2` to `sql-reference`
3. modify build extension github action to run `docs/build_help_zip.sh`

SHOW-LOAD-PROFILE

Name

SHOW LOAD PROFILE

Description

该语句是用来查看导入操作的Profile信息，该功能需要用户打开 Profile 设置，0.15 之前版本执行下面的设置：

SET is_report_success=true;

0.15 及之后的版本执行下面的设置：

SET [GLOBAL] enable_profile=true;

语法：

show load profile "/";

show load profile "/[queryId]"

这个命令会列出当前保存的所有导入 Profile。每行对应一个导入。其中 QueryId 列为导入作业的 ID。这个 ID 也可以通过 SHOW LOAD 语句查看拿到。我们可以选择我们想看的 Profile 对应的 QueryId，查看具体情况

Example

列出所有的 Load Profile

mysql> show load profile "/";
+---------+------+-----------+------+-----------+---------------------+---------------------+-----------+------------+
| QueryId | User | DefaultDb | SQL  | QueryType | StartTime           | EndTime             | TotalTime | QueryState |
+---------+------+-----------+------+-----------+---------------------+---------------------+-----------+------------+
| 10441   | N/A  | N/A       | N/A  | Load      | 2021-04-10 22:15:37 | 2021-04-10 22:18:54 | 3m17s     | N/A        |
+---------+------+-----------+------+-----------+---------------------+---------------------+-----------+------------+
2 rows in set (0.00 sec)
