useEffect documentation missing variable arryas

With colleges, we were talking about how reacts useEffect compares the input array and after diving into React code I found out that its length can't vary and didn't find the note in docs.

https://github.com/facebook/react/blob/master/packages/shared/areHookInputsEqual.js

Here's the code chunk with warning handling but it may be good to mention that in docs.

You all are awesome and I love what you are doing with React. Keep rocking 👌

Thanks also @linde12 for bouncing the ideas which led to mutual conclusion

先阅读链接的 packages/shared/areHookInputsEqual.js 代码，然后在 React 文档网站中找到 useEffect 文档。记录依赖数组的长度不能变化，并在相关的 useEffect 指南明确说明这一限制后，将工作视为完成。
