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`

FROM data_source
[data_source_properties]

  1. [db.]job_name

    Specifies the job name to modify.

  2. tbl_name

    Specifies the name of the table to be imported.

  3. job_properties

    Specifies the job parameters that need to be modified. Currently, only the modification of the following parameters is supported:

    1. desired_concurrent_number
    2. max_error_number
    3. max_batch_interval
    4. max_batch_rows
    5. max_batch_size
    6. jsonpaths
    7. json_root
    8. strip_outer_array
    9. strict_mode
    10. timezone

    1. kafka_partitions
    2. kafka_offsets
    3. kafka_broker_list
    4. kafka_topic

    Note:

    1. kafka_partitions and kafka_offsets are used to modify the offset of the kafka partition to be consumed, only the currently consumed partition can be modified. Cannot add partition.

Example

  1. Change desired_concurrent_number to 1

    ALTER ROUTINE LOAD FOR db1.label1
PROPERTIES
(
    "desired_concurrent_number" = "1"
);

  2. Modify desired_concurrent_number to 10, modify the offset of the partition, and modify the group id.

    ALTER ROUTINE LOAD FOR db1.label1
PROPERTIES
(
    "desired_concurrent_number" = "10"
)
FROM kafka
(
    "kafka_partitions" = "0, 1, 2",
    "kafka_offsets" = "100, 200, 100",
    "property.group.id" = "new_group"
);
