dotnet new maui App Can't Be Published For iOS

[eerhardt]

Steps to Reproduce

1. dotnet new maui
2. dotnet publish -c Release -f net6.0-ios -r ios-arm64

Expected Behavior

The app should publish successfully.

Actual Behavior

/Users/eerhardt/git/maui/bin/dotnet/packs/Microsoft.MacCatalyst.Sdk/15.2.300-preview.13.1/targets/Xamarin.Shared.Sdk.targets(1538,3): The RuntimeIdentifier 'ios-arm64' is invalid. [/Users/eerhardt/DotNetTest/MauiTest/NoHosting/NoHosting.csproj]

From looking at the binlog, it appears that the _GenerateRestoreGraph target is running for each TargetFramework listed in TargetFrameworks. The default dotnet new maui .csproj has:

<TargetFrameworks>net6.0-android;net6.0-ios;net6.0-maccatalyst</TargetFrameworks>

And when the target is running for net6.0-maccatalyst, it is failing here:

Turns out I've already filed this in the dotnet/sdk repo: dotnet/sdk#21877, so I'm closing this one if favor of the dotnet/sdk one.
