序列化协议升级

如果消费方也是新版本，但是似乎没办法按照文档所说的存在优先级的判断。如：配置dubbo.provider.prefer-serialization=fury，fastjson2。此时如果消费方不存在fury。则会报错。代码里只是简单获取第一条而已，并没有校验是否存在该序列化方式的实现.
Optional serializations = allSerializations(url).stream().findFirst();

Start by locating the implementation containing `allSerializations(url).stream().findFirst()` and compare it with the documentation for `dubbo.provider.prefer-serialization`. Reproduce the case where `fury` is unavailable and `fastjson2` is configured, then verify that the observed selection behavior matches the documented priority and add or update the relevant regression coverage if the project provides it.
