About the type definition issue on StyleDeclarationMap

**TypeScript Version:** 3.7.5
**Aphrodite Version:** 2.4.0
When I using StyleSheet create function
```javascript
const style = StyleSheet.create({
container: {
}
})
```
I found out that VS Code is not able to give me any autocomplete suggestion on those CSS properties, since they think StyleDeclarationMap is a type of 'any'

but it is not

I have changed typescript version and modified my tsconfig file, but nothing make it work.

I wonder how can I fixed this issue?

Start by inspecting the type definitions used by StyleSheet.create, especially StyleDeclarationMap, and reproduce the missing CSS-property autocomplete with TypeScript 3.7.5 and Aphrodite 2.4.0. Done means VS Code offers CSS property suggestions for styles created through StyleSheet.create.
