Fix(Sample): Archiving failing due to duplicate build outputs

[kieran-osgood-shopify]

What changes are you making?

The sample is failing to archive for iOS due to an error regarding duplicate outputs

error: Multiple commands produce '/Users/ko/Library/Developer/Xcode/DerivedData/Build/Intermediates.noindex/ArchiveIntermediates/ReactNative/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/React-Core_privacy.bundle'
    note: Target 'React-Core-f955c501-React-Core_privacy' (project 'Pods') has create directory command with output '/Users/ko/Library/Developer/Xcode/DerivedData/Build/Intermediates.noindex/ArchiveIntermediates/ReactNative/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/React-Core_privacy.bundle'
    note: Target 'React-Core.common-React-Core_privacy' (project 'Pods') has create directory command with output '/Users/ko/Library/Developer/Xcode/DerivedData/Build/Intermediates.noindex/ArchiveIntermediates/ReactNative/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/React-Core_privacy.bundle'

I fixed this by updating the sample Podfile to include the pod within the correct Target.
There is a nice by-product from this where the previous workaround to this on the "React-Core-RCTI18nStrings" and "React-Core-AccessibilityResources" are no longer necessary simplifying the Podfile

I also added in the correct merchant id entitlement which fails the xcode build every time
