Fix INFOPLIST_FILE paths in ios/RIBs.xcodeproj after the move

Moving the Carthage project under ios/ (#55) rehomed the group paths but left
the RIBs and RIBsTests INFOPLIST_FILE build settings pointing at
`RIBs/Info.plist` / `RIBsTests/Info.plist`, which now resolve to non-existent
`ios/RIBs/...` paths and break `carthage build` (exit 65, missing build input
file). CI did not catch it because only Carthage builds this project — SPM uses
Package.swift and the Example build uses its own project. Point them one level
up (`../RIBs/Info.plist`, `../RIBsTests/Info.plist`).
