Avalonia 12 support

[hatulaile]

Avalonia has now been released up to 12.rc1, are there any plans to support version 12?

I have a fork, that I include directly in my projectd using .NET 11 and avalonia 12
https://github.com/flucas1/TreeDataGrid.Avalonia

However drag and drop is disabled, as there are some rework to do.

I'll work on adding Avalonia 12 compatibility and plan to do it within the next week.

Good news - I've published TreeDataGrid.Avalonia 12.0.0 on NuGet.
It targets .NET 8.0 and .NET 10.0 and depends on Avalonia >= 12.0.1.

The demo project runs fine and all unit tests are still passing. That said, I'm not yet using Avalonia 12 in my own projects, so I haven't stress-tested it heavily in real-world scenarios. If you update and run into any problems, please drop a comment here
