Pull request overview

This PR enables iOS Smart App Banners for selected World Service services by configuring an iTunesAppId and simplifying the banner render gate to depend on the presence of that ID (and being on a canonical/non-AMP page).

Changes:

• Add iTunesAppId: 6761256736 to the Mundo, Hindi, Arabic, and Russian service configs.
• Remove hasAppleItunesAppBanner from MetadataProps and stop passing it through MetadataContainer.
• Update renderAppleItunesApp to render based on iTunesAppId + canonicalLink + !isAmp only.
