[Typo]: editing `serverUrl` in the sandbox as directed does not cause the Effect to re-synchronize

Summary

These two sentences at https://react.dev/learn/lifecycle-of-reactive-effects#how-react-verifies-that-your-effect-can-re-synchronize don't make sense for the given example.

For example, try editing the serverUrl in the sandbox above while the chat is open. Notice how the Effect re-synchronizes in response to your edits to the code.

Details

In that sandbox example, serverUrl is not a reactive value.

Editing its value in the sandbox does not cause the Effect to re-synchronize.

从 React 文档中链接的部分开始，检查 chat 示例的 sandbox，尤其是 serverUrl 的定义和变更方式。将指令与观察到的行为进行比较，然后修改这两个句子，使其准确描述 Effect 何时重新同步；链接页面不应再声称 sandbox 无法演示的内容。
