Chart data type is incorrect in 4.1.2

### Expected behavior

The types for the Chart object has `data: ChartData`, but it should be `data: ChartData;` instead to have the dataset typed properly within the data. Otherwise it's the default types from `DefaultDataPoint`

```
export declare class Chart<
TType extends ChartType = ChartType,
TData = DefaultDataPoint,
TLabel = unknown
> {
// ...
data: ChartData;
// ...
```

### Current behavior

```
export declare class Chart<
TType extends ChartType = ChartType,
TData = DefaultDataPoint,
TLabel = unknown
> {
// ...
data: ChartData;
// ...
```
