Enable Dismissal of Sliver Modal Sheet on Downward Drag at Scroll Edge

[sheeroo]

when using a sliver modal sheet with scrollable content like a list, dismissing the modal by dragging it down isn't possible once the scrollable content has reached its top edge (meaning it can't scroll up any further).

This behavior differs from common interaction patterns in other apps, where a downward drag at the top of a scrollable list dismisses the modal.

Adding this feature would enhance the modal's usability by allowing it to be dismissed with a downward swipe when the scroll position is at the top edge.

Hiii, thanks for the quick reply and the amazing work. You are right I was using an older version, sorry for that. I tried this implementation but I was a little disappointed with the result. The drag animation does't follow the finger quite well while dragging down. I think the user experience is quite off. The package smooth_sheets does a really good job with the drag animation if that provides any help. Again thanks for all the work you have put into this :)
