[Typo]: In Sharing State Between Components

Summary

When explaining state lifting up, there's a small error in the example function for the second step : Pass hardcoded data from the common parent:

function Panel({ title, children, isActive }) {
  return (
    <section className="panel">
      <h3>{title}</h3>
      {isActive ? (
        <p>{children}</p>
      ) : (
        <button onClick={() => setIsActive(true)}>
          Show
        </button>
      )}
    </section>
  );
}

The onClick calls setIsActive, but since there's no state declared, it should be removed.

開啟 Sharing State Between Components 頁面，檢查第二個步驟的範例「Pass hardcoded data from the common parent.」移除對 setIsActive 的 onClick 呼叫，因為沒有宣告對應的 state，並確認範例不再參照該 setter。
