Fix "paused on debugger" overlay icon

Summary:
This icon was broken by D65457771, identified in [OSS testing for the 0.77 release](reactwg/react-native-releases#724).

By explicitly setting the image for the `Disabled` state to the same as `Normal`, we get the same behaviour as the deprecated [`adjustsImageWhenDisabled = NO`](https://developer.apple.com/documentation/uikit/uibutton/adjustsimagewhendisabled?language=objc) without the need for `configurationUpdateHandler`.

Changelog: [iOS][Fixed] Restore "Paused in debugger" overlay icon
