Subject: [PATCH] Show the iOS sheet grabber only on a sheet that can be
 resized

The bottom sheet forced `.presentationDragIndicator(.visible)`, so every
sheet had a grabber, also one with a single detent that can't be dragged
to another height. Apple's HIG (Sheets) puts a grabber in a resizable
sheet: it shows the sheet can be dragged to resize and lets VoiceOver
resize it. On a sheet that can't resize it promises something that
isn't there.

`.automatic` leaves it to the system, which shows the grabber on the
default "medium,large" sheet and hides it on a single detent ("large",
"fit"). Swipe-down to dismiss works the same either way.
