Generic type support for dataItem in components (Eg: Grid)

[Grant]

Hi team,

I'm working with KendoReact Grid and need to strongly type the `dataItem` property in custom cell components. Currently, `GridCustomCellProps` has `dataItem: any`, which loses type safety.

I've been creating wrapper types like:

// Base generic type for any Kendo component with dataItem
type WithTypedDataItem<K, D> = Omit<K, 'dataItem'> & { dataItem: D };

// Specific type aliases for common use cases
type TGridCustomCellProps<T> = WithTypedDataItem<GridCustomCellProps, T>;
// ... others

Questions:
1. Is there a native/commonly accepted way to type `dataItem` that I'm missing?
2. Are there plans to add generic type parameters to `GridCustomCellProps` (e.g., `GridCustomCellProps<TDataItem>`) in future releases?

This would improve type safety across Grid, ComboBox, DropDownList, and other components that use dataItem.

Thanks,
Grant
