Border specific top right bottom left options don't exist in Sketch
Filling an issue before updating the Doc, just in case I missed something here.

But `borderTopLeftRadius`, `borderTopRightRadius`, `borderBottomLeftRadius`, `borderBottomRightRadius`, `borderTopWidth`, `borderTopWidth`, `borderRightWidth`,etc. won't have any effect in Sketch as these options are not implemented. (See [Sketch Doc about borders](https://www.sketchapp.com/learn/documentation/styling/borders/))

**Sketch version:** 44.1

[Doc](https://github.com/airbnb/react-sketchapp/blob/master/docs/styling.md) should maybe have a ⛔️ next to those options.
