Description:
Document shows(https://dev.mysql.com/doc/refman/8.0/en/clone-plugin-options-variables.html#sysvar_clone_d...):
As of MySQL 8.0.27, concurrent DDL is permitted on the donor during a cloning operation if clone_block_ddl variable is enabled (the default).

The default value of clone_block_ddl is OFF, and clone_block_ddl should be OFF if we want concurrent DDL is permitted on the donor during a cloning operation.

How to repeat:
At clone_block_ddl variable describes:
https://dev.mysql.com/doc/refman/8.0/en/clone-plugin-options-variables.html#sysvar_clone_b...

Default Value is OFF.

Suggested fix:
As of MySQL 8.0.27, concurrent DDL is permitted on the donor during a cloning operation if clone_block_ddl variable is enabled (the default).

change into------->
As of MySQL 8.0.27, concurrent DDL is permitted on the donor during a cloning operation if clone_block_ddl variable is OFF (the default).
