Issue Description

I'm getting an error when trying to install Xamarin on a Mac OS 14 machine via the following script:
 
brew install --cask xamarin-ios
brew install --cask xamarin-android

The error message is

Warning: xamarin-android has been deprecated because it is discontinued upstream! It will be disabled on 2025-08-20.

Error: Download failed on Cask 'xamarin-android' with message: Download failed: https://dl.xamarin.com/MonoforAndroid/Mac/xamarin.android-13.2.2.0.pkg

It looks like the Android file is no longer present at the legacy URL.
