RC Configure ephemeral URLSession for iOS 18.4 simulator

[tusharkhandelwal8]

Resolved an issue where RCN Config fetch was failing earlier on iOS 18.4 simulators; this is now fixed. Addressed a bug in URLSession causing network requests to fail in the iOS 18.4 and visionOS 2.4 simulators (included with Xcode 16.3). The workaround implemented is to use an ephemeral URLSession configuration when running in these simulators. See https://developer.apple.com/forums/thread/777999 for more details. Behavior on older simulators and physical devices is unchanged.
