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

This statement is used to view the Profile information of the import operation. This function requires the user to open the Profile settings. The versions before 0.15 perform the following settings:

SET is_report_success=true;

Versions 0.15 and later perform the following settings:

SET [GLOBAL] enable_profile=true;

grammar:

show load profile "/";

show load profile "/[queryId]"

This command will list all currently saved import profiles. Each line corresponds to one import. where the QueryId column is the ID of the import job. This ID can also be viewed through the SHOW LOAD statement. We can select the QueryId corresponding to the Profile we want to see to see the specific situation

Example
