antd中Steps步骤条设置文字标识在图标的下面

可以通过设置`labelPlacement`属性为`bottom`来实现文字标识在图标的下面，示例代码如下：

import { Steps } from 'antd';

const { Step } = Steps;

function App() {
  return (
    <Steps labelPlacement="bottom">
      <Step title="Step 1" description="This is a description." />
      <Step title="Step 2" description="This is a description." />
      <Step title="Step 3" description="This is a description." />
    </Steps>
  );
}

export default App;
