Update Release 5.1.6 with new xcframework zips

[nan-li]

Motivation

• The zips were previously generated before the xcframeworks were signed so the zips didn't contain code signatures
• These new ones are generated after the xcframeworks are signed

Only affects SPM Tested cocoapods still works with release 5.1.6 Tested SPM still works with release 5.1.6 after these changes, and unzipping shows the code signatures

How it was tested: SPM

• Uploaded these 9 zips to the Release 5.1.6
• Used the xcframework PR branch https://github.com/OneSignal/OneSignal-XCFramework/pull/87 as the branch to add the dependency via SPM to sample project
• Run app and confirm dependency

Cocoapods

• Add version 5.1.6 to podfile and install
• Run the example app
