Pull request overview
This PR removes support for .NET 9 from the net11.0 branch, transitioning it to an unsupported/out-of-support status. With this change, only .NET 10 remains as a supported version (with .NET 11 being prepared as a future version).
Key Changes:
- Updated test infrastructure to verify .NET 9 builds now fail with appropriate out-of-support error messages
- Removed all .NET 9 SDK package dependencies across multiple Xcode/API versions
- Removed .NET 9 API version entries from the supported versions configuration
