There are a few steps here:
1. We need to confirm that a Translatewiki change to CFBundleDisplayName (example here from zh-hans) will result in an update to the appropriate change in Wikipedia/Localizations/{langCode}.lproj/InfoPlist.strings file when a Translatewiki PR is opened. The last time one of these files was changed was 2017, so I suspect something is broken on the Translatewiki side to prevent this change. - This is fixed, see https://github.com/wikimedia/wikipedia-ios/pull/4807
- Once that's working, we need to be sure our import script appropriately applies those changes to the Wikipedia/iOS Native Localiations/{languageCode}.lproj/InfoPlist.strings file. We also need to be sure it applies to the fastlane/metadata/{langCode}/name.txt file. It seems like this is already a part of our import script (see here), but this flow hasn't been tested in forever.
- Once that's all in place, we need to add a step to our Xcode Cloud post-build script that uploads metadata via fastlane to App Store Connect. Note: This step has a related volunteer PR that should be merged or closed at the same time: T357323).
