Other information

Merge the src-tauri/Info.plist and src-tauri/Info.ios.plist files with the iOS project Info.plist file to allow extending the IPA configuration, similar to the macOS implementation.

@FabianLars raised a possible issue with merging Info.plist for both macOS and iOS, but I couldn't think of anything really.. I feel like we could also read Info.macos.plist and let the user decide what's get shared to both platforms.

even if there aren't any actual consequences (that'd crash something or something) they'd still pollute each other right? I mean, we're only talking about a few (k)bytes but v2 already has much larger binaries so every bit counts i guess?
