ti.storekit module for iOS 64 bit

* If you are updating a module to 64 bit then bump the 2nd number in the version `3.1.0`
* If the module has already been updated to 64 bit and you are adding architectures to the manifest then bump the 3rd number in the version `3.1.1`
* If you are doing both in one, just update the 2nd number in the version `3.1.0`, there is no need to bump both
