Fix OnyxAccordionItem not closing when :open receives a false

[ChristianBecker02]

Description

I am currently trying to add a open all, close all AccordionItems button, and stumbled over the fact that when the :open parameter is set to true, the AccordionItem is correctly opening, but the reverse part - setting it to false does not close the AccordionItem.

Manually it works and in the showcase of the component is marked as it can be toggled between true and false.

But its not working with ref, computed or else and also not with a simple button in the playground.
