👑 [需求] schemaform 中组件 group 中的gutter 属性是写死的，不能只定义

提问前先看看：

### 🔩 所属模块或组件

BetaSchemaForm -> group (packages/form/src/components/Group/index.tsx)

### 🥰 需求描述

```tsx
// packages/form/src/components/Group/index.tsx:98
const [childrenDoms, hiddenDoms] = useMemo(() => {
const hiddenChildren: React.ReactNode[] = [];
const childrenList = React.Children.toArray(children).map(
(element, index) => {
if (React.isValidElement(element) && element?.props?.hidden) {
hiddenChildren.push(element);
return null;
}
if (index === 0 && React.isValidElement(element) && autoFocus) {
return React.cloneElement(element, {
...(element.props as any),
autoFocus,
});
}
return element;
},
);

return [

{childrenList}
,
hiddenChildren.length > 0 ? (

) : null,
];
}, [children, RowWrapper, Wrapper, autoFocus]);
```

`` 这里没有提供自定义 props 传入，导致不能修改row相关属性

Start in packages/form/src/components/Group/index.tsx, especially the useMemo block around line 98 where RowWrapper is rendered. Trace how Group and RowWrapper receive row-related props, then make the requested customization possible for the group’s row attributes and gutter. Done means callers can define those properties instead of relying on the hard-coded behavior; verify the affected form group behavior.
