docs(cn): translate "separate events from Effects" section in hooks.md

[Sophran-fbj]

Summary

Translate the remaining English snippet in src/content/reference/react/hooks.md about separating events from Effects.

Changes

- You can also separate events from Effects:
+ 你也可以将事件从 Effect 中分离：

- - [`useEffectEvent`](/reference/react/useEffectEvent) creates a non-reactive event to fire from any Effect hook.
+ - [`useEffectEvent`](/reference/react/useEffectEvent) 创建一个不具响应性的事件，可以在任意 Effect Hook 中触发。

The useEffectEvent page itself was already translated in #1813 and #1860, but this short paragraph on the Hooks index page was missed.
