使用 Zookeeper 作为注册中心文档勘误

这里有一个错误的地方，dubbo-spring-boot-starter不会添加zookeeper相关客户端的依赖，应该是下面的dubbo-zookeeper-spring-boot-starter 或 dubbo-zookeeper-curator5-spring-boot-starter会添加zookeeper相关客户端的依赖，应该是笔误哦
文档地址：https://cn.dubbo.apache.org/zh-cn/overview/mannual/java-sdk/tasks/service-discovery/zookeeper/

Open the linked Zookeeper service-discovery documentation page and inspect the dependency names in the section shown in the issue. Confirm which starter provides the Zookeeper client dependency, correct the typo, and verify that the rendered page names the appropriate starter options.
