How to pin MAUI publishable by xcode 15.4?

My publish is failing with the following error:

Error: /Users/builder/azdo/_work/1/s/xamarin-macios/src/build/dotnet/ios/generated-sources/UIKit/UITextView.g.cs(773): error MT4162: The type 'UIKit.NSAdaptiveImageGlyph' (used as a parameter in UIKit.UITextView.InsertAdaptiveImageGlyph) is not available in iOS 17.5 (it was introduced in iOS 18.0). Please build with a newer iOS SDK (usually done by using the most recent version of Xcode)

I'm targeting net8-ios. From what I find online this is because the build server is installing a workload version which is targeting iOS 18, which cannot be built on XCode 15.4. I also read that in net8 I can specify the target mau using Microsoft.Maui.Controls package version - I've added it and specifically selected 8.0.93 version which does not target net8-ios18.0. Still fails.

Ok, as usually, soon after writing I've found a solution. It turns out that my worker's dotnet version was updated and scoping wasn't being properly applied from the global.json file in the solution. While this is frustrating the workaround in GitHub workers is simply to run dotnet like this: ~/.dotnet/dotnet ... in all steps.
