Update constant name in useImperative example

[HiteshChoudhary0098]

User Imperative example has to same ref name in child and in the parent. Causing confusion while understanding the concept.

function FancyInput(props, ref) { const **inputRef** = useRef(); useImperativeHandle(ref, () => ({ focus: () => { inputRef.current.focus(); } })); return <input ref={**inputRef**} ... />; } FancyInput = forwardRef(FancyInput);

`In this example, a parent component that renders <FancyInput ref={inputRef} /> would be able to call inputRef.current.focus().'
