Fix/Shows dependent questions of multiple_checkboxes fields

[NuriaExtremadouro]

Description

• Fixes a bug by which the dependent questions of multiple checkboxes weren't showing.

Related Issue

• Found when working on ALD-22.

Motivation and Context

• We had a multiple checkbox field with a dependent question that should show when we select the "Other" checkbox.
• When we selected the "Other" checkbox, the dependent question wasn't showing. As in, the multiple checkboxes field wasn't triggering the ConditionalQuestion because no state changes were detected.
• But if we made a selection in any other type of field (such as a select) that had its own dependent questions, it would show the dependent questions of the multiple checkboxes as well. As in, triggering the select field was triggering ConditionalQuestion method. And that execution would show any dependent questions that should be visible, including the one from the multiple checkboxes.
• The reason was because the onChange event of the QuestionMultipleCheckboxes was set to execute disableOthers on a given condition. However, even though this condition was working, it was still causing the form to not detect any changes on the multiple checkboxes. Setting the onChange event to anything would keep causing this bug, so now the Checkbox component is configured conditionally.

How Has This Been Tested?

Verified that both the dependentQuestions and the disableOthers configs work for the multiple checkboxes.
