dubbo-serialization-kryo:1.0.0中依赖的dubbo-common-extensions为SNAPSHOT版本

模块：dubbo-serialization-kryo
版本：1.0.0
dubbo官方文档中使用kryo要求添加依赖，版本为1.0.0
而maven官方仓库中该版本依赖的dubbo-common-extensions为SNAPSHOT版本

为什么上传到maven官方仓库的版本还依赖SNAPSHOT版本的包呢？
maven官方库中没有该SNAPSHOT包，拉取该包会报错
`Could not find artifact org.apache.dubbo.extensions:dubbo-common-extensions:jar:3.0.0-SNAPSHOT`

Inspect the dubbo-serialization-kryo 1.0.0 publication and its Maven dependency metadata, focusing on the reference to dubbo-common-extensions:3.0.0-SNAPSHOT. Verify the dependency can resolve from Maven Central after the change, and confirm the documented Kryo dependency no longer fails to download.
