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`
