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`

Name

ALTER SYSTEM DROP BACKEND

Description

This statement is used to delete the BACKEND node (administrator only!)

grammar:

ALTER SYSTEM DROP BACKEND "host:heartbeat_port"[,"host:heartbeat_port"...]

illustrate:

host can be a hostname or an ip address
heartbeat_port is the heartbeat port of the node
Adding and deleting nodes is a synchronous operation. These two operations do not consider the existing data on the node, and the node is directly deleted from the metadata, please use it with caution.

Example

Delete two nodes

ALTER SYSTEM DROP BACKEND "host1:port", "host2:port";

Keywords

ALTER, SYSTEM, DROP, BACKEND
