Description

We should be able to control the Select component. An initialActiveItem could be the solution to keep the current key events mechanism operational ;) This feature is required when we use Select component with a form builders like Formik.

Research direction
Examine the Select component implementation in the Blueprint repository (likely in packages/core/src/components/select/select.tsx). Review existing props and how active item is managed via key events. Implement a new prop `initialActiveItem` that sets the initial active item. Ensure it integrates with current state and does not break existing behavior. Update tests and documentation accordingly.
