🧐[问题] Schema Form的valueType:formList，renderFormItem失效

### 🧐 问题描述
我在Schema Form的使用valueType:formList，在renderFormItem想要用defaultRender，修改“新增一行”的功能，但使用formList，但renderFormItem直接无法使用了。但其他简单的valueType格式就可以使用
### 💻 示例代码
{
title: field.fieldName + "<" + field.fieldKey + ">",
dataIndex: field.fieldKey,
valueType: 'formList',

columns: [
{
valueType: 'group',
columns: childrenColumns,
},
{
dataIndex: 'batchNo',
hideInForm: true
},
],
fieldProps: (form, config) => {
return {
creatorButtonProps: showIsSource ? false : {creatorButtonText: `新建一行${field.fieldName}`},
copyIconProps: false,
}
},
renderFormItem: (schema, config, form) => {
console.log(schema)
console.log(config)
console.log(form)
return <>
{config.defaultRender()}

add()} block icon={}>
Add sights



}
};

Start with the Schema Form valueType formList path and the renderFormItem example in this issue, then reproduce the behavior with defaultRender and the custom add-row button. Done means renderFormItem works for formList as it does for simpler value types without breaking the existing formList controls.
