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

Summary:
Judging from the original [commit](https://github.com/facebook/react-native/commit/4c4948b6e83208cd517dd977b3462b1959505e1d), 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 (https://github.com/facebook/react-native/commit/2c5a966054c2a80d63aa9c2c2a234a80a02918cf)
