Summary:
I noticed that typescript type for `onChange` event of `<Switch/>` was incorrect
```tsx
<Switch
onChange={(event) => {
// TS
event.value; // boolean
event.nativeEvent.value; //TS2339: Property 'value' does not exist on type 'Event'.
// JS
console.log(event.nativeEvent); // {value:false,target:87}
console.log(event.value); // undefined
}}
/>
```
## Changelog
[General] [Changed] - Typescript: update incorrect `SwitchChangeEvent` type
