fix(iOS): Pressable blockNativeResponder box

[mdjastrzebski]

Summary:

Fix blockNativeResponder prop workings on iOS. It already works fine on Android.

Before:

block.native.responder.before.mp4

Fixes: #56061

In our case this bug manifested in the following scenario:

In our iPad application the iOS 26 system scroll-to-top area are is overlapping with navigation bar. When pressing buttons in the top bar the iOS invokes native behavior of scroll to the top, as Pressable-based buttons are non consuming the touch and it gets delivered native views.

See the red box for scroll-to-top area:

The same issue has been reported in React Navigation repo: react-navigation/react-navigation#12843
