[docs] useMemoizedFn cannot replace useCallback when functions called during render

[MeetzhDing]

In the document: useMemoizedFn

Hooks for persistent functions. In theory, useMemoizedFn can be used instead of useCallback.

In some scenarios, we need to use useCallback to cache a function, but when the second parameter deps changes, the function will be regenerated, causing the function reference to change.

But according react rfcs useEvent, a memoized function may case error in rendering, e.g. not rerender as expected.

I suggested to declare this situation in the document.
