fix: expose ref on ActionSheetProvider for statically invoking (#283)

This fixes an unknown breaking change from 4.0.0 where attempting to put a ref directly on `ActionSheetProvider` would error. For simplicity, the ref on that component will now return an object containing `showActionSheetWithOptions()`, but for backwards compatibility `getContext()` is also available.
