🐛[BUG] ProFormList在单个新record时，ProFormSelect 的 transform不会触发

### 🐛 bug 描述
ProFormList在单个新record时，ProFormSelect 的 transform不会触发
反之，多个新record时，transform正常触发

### 📷 复现步骤
```
transform={(value: string[]) => {
console.log('transform')
console.log(value)
return {prodLine: value[0]}
}}
```
在创建新时，尝试只新增一个record，然后submit
然后尝试新增多个record，然后submit

### 🏞 期望结果
无论新增多少record都好，transform在submit时候都要正常触发

### 💻 复现代码

```

{(_meta, currIndex, _action, _count) => {
return (

tags.map(str => str.toUpperCase())}
fieldProps={{
fetchDataOnSearch: false,
showSearch: true,
maxCount: 1,
tagRender: (props) => {props.label}
}}
transform={(value: string[]) => {
console.log('transform')
console.log(value)
return {prodLine: value[0]}
}}
rules={[
{required: true, message: ''}
]}
/>

)
}}

```

### © 版本信息

"antd": "^5.25.0",
"@ant-design/pro-components": "^2.8.2",

### 🚑 其他信息


Start with the ProFormList and ProFormSelect implementation, then reproduce the submitted example using antd 5.25.0 and @ant-design/pro-components 2.8.2. Compare submission with one new record against multiple new records; done means the select transform runs consistently in both cases and returns the expected prodLine value.
