🤔 [QUESTION]条形图无法展示图表标题

## 给条形图配置title后，无法展示

### 图表配置
`
import { Bar } from '@ant-design/plots';

const Chart = ({ dataSource }) => {
const config = {
xField: 'value',
yField: 'label',
color: ({ label }: Record) => {
if (label === '收入') {
return '#F34B45';
}
if (label === '支出') {
return '#2EA223';
}
return '#5254CC';
},
title: {
visible: true,
text: '年度累计（万元）',
},
tooltip: {
title: '年度累计（万元）',
showTitle: true,
},
};

return (

);
};
export default Chart;
`
### 展示截图

### 期望效果
标题正常展示

* **G2Plot Version**: @ant-design/plots 1.2.6

Start by reproducing the issue with the Bar component, the shown title configuration, and @ant-design/plots 1.2.6. Trace how the title option is handled and verify that the chart title renders as expected without breaking the tooltip behavior.
