radio组件options.value和v-model的值类型对应

[trague]

1.9.2

Reproduction link

https://didi.github.io/cube-ui/#/zh-CN/docs/radio

Steps to reproduce

radio.props.options[i].value 设置成Number报错

[Vue warn]: Invalid prop: type check failed for prop "value". Expected String, got Number.

What is expected?

文档说明radio组件 Props.options[i].value可以是[Number, String], 但是v-model绑定的value只能是String

What is actually happening?

不会出错
