Update ViewTransition fixture to include bigger buttons/swipe (#32656)

I made the button a bit bigger and moved the swipe recognizer around the
whole screen. Typically these are used around the whole content without
any affordances and not as a standalone scrubber. Ideally the swipe
would be able to be inside the animating content but it can't yet due to
[this Safari bug](https://bugs.webkit.org/show_bug.cgi?id=288795).

Added back some paragraphs so that scrolling can be tested properly. It
appears it's possible to get the swipe to be a bit misaligned if you
scroll enough on iOS.
