fix: always run pod install to generate codegen files

pod install generates files into node_modules (like RCTThirdPartyFabricComponentsProvider.mm)
that are required for the build. These files are generated even when Pods cache exists,
so we must always run pod install. The cache still provides significant speedup since
all pods are already downloaded and built.
