🐛[BUG]cdn引入pro-form和antd，pro-form插入的样式覆盖了定制的主题色

### 🐛 bug 描述

 通过cdn的方式引入`antd`和`@ant-design/pro-form`，引入成功后，发现原本定制的主题色，被覆盖成了默认的主题色。
 翻了一下`@ant-design/pro-form`的源码，发现是它在``里插入了很多``，包含默认的样式，导致定制的主题色被覆盖。

1. config.ts
```javascript
{
//...other config
antd: {
disableBabelPluginImport: true
},
externals: {
react: 'React',
'react-dom': 'ReactDOM',
'@ant-design/pro-form': 'ProForm',

],
}
```

### 🏞 期望结果

<!--
描述你原本期望看到的结果
-->
&emsp;因为我已经引入了`antd.min.css`，所以默认的样式应该也都有。`@ant-design/pro-form`为什么要再专门创建并添加这些样式呢？
&emsp;期待结果：`@ant-design/pro-form`不添加这些默认的样式
