chore: Remove invalid aria-hidden prop from layout wrapper

[dougfabris]

Proposed changes (including videos or screenshots)

The error below is popping up, because we're using an invalid aria-hidden to the layout wrapper when displaying a modal, telling assistive technologies to not consider the main tree when the modal is on the screen. Since we do use a proper strategy to block the focus already, its not necessary to use this aria-hidden property.
