fix SwipeAction props type defination about left and right

[JackClown]

The default type defination of SwipeAction buttons is ?SwipeoutButtonProperties[], and there is no style property of SwipeoutButtonProperties.
So when I use literal object which has a style prop for right or left buttons, there will be an error: Object literal may only specify known properties, and 'style' does not exist in type 'SwipeoutButtonProperties'
Example:

<SwipeAction
  autoClose
  style={{ backgroundColor: 'transparent' }}
  right={[
    {
      text: 'More',
      style: { backgroundColor: 'orange', color: 'white' }
    },
    {
      text: 'Delete',
      style: { backgroundColor: 'red', color: 'white' }
    }
  ]}
>
  <List.Item extra='extra content'>Simple example: left and right buttons</List.Item>
</SwipeAction>
