ItemMap Usage

There are three items in this questionnaire, therefore the itemMap Record<linkId, Omit<QuestionnaireItem, 'item'>> will have three items and their properties (excluding item.item).

This hook is useful for quickly accessing QuestionnaireItem properties via linkId without having to traverse the entire Questionnaire structure.
