Fix Catalyst @availablity checks in RCTPullToRefreshViewComponentView.mm (#35673)

Summary:
Judging from the original [commit](4c4948b), the availability check is probably for Catalyst, not macOS.  That matches the [apple documentation](https://developer.apple.com/documentation/uikit/uiscrollview/2127691-refreshcontrol?language=objc) as well (though we need 13.1, not 13).

To avoid needing to introduce a diff in React Native macOS (where we actually compile for macOS and not Mac Catalyst) let's fix the availability check to be more accurate. Changing `macOS` to `MacCatalyst` should be supported as per https://docs.swift.org/swift-book/ReferenceManual/Attributes.html#ID348 (2c5a966)
