ariaQuestion content in example.json

Subject of the issue/enhancement/features

Could the text 'Question text specifically for screen readers.' be removed from the ariaQuestion json element please. Just so there isn't a risk of this being added in redundantly when it isn't needed, or it being left in accidently on accessible courses where ariaQuestion text isn't required.

I agree with removing the ariaQuestion placeholder text for the same reasons.

This applies to all question components: Slider, confidenceSlider, textInput, matching.
GMCQ is already empty.
