[interactive_media_ads] Pin iOS dependency maximum (flutter#10349)

GoogleInteractiveMediaAds [released 3.28.10](googleads/swift-package-manager-google-interactive-media-ads-ios@7f38970) which dropped iOS 13 and 14, breaking our tree. This sets a max version on the dependency to avoid picking up a version that is not compatible with our wrapper's iOS version support.

Longer term we can explore expanding the range, but this is non-trivial for Swift Package Manager, so this is the simplest way to fix the tree and clients in the short term.
