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`
