Fixes BHV-9597 - Expandable Picker needs to handle dynamic data

## Issue
The current solution for handling dynamic data in Expandable picker enforces developers to create a custom component.

## Fix
Add a new component to the framework that wraps a DataRepeater to allow a data-driven expandable picker
