xarray-datatree removal

[Antonio Valentino]

Dear Sebastiaan, dear all,
I'm going to request the removal from unstable of the xarray-datatree 
source package.

The feature provided by xarray-datatree have been now included in xarray 
itself starting form v2024.10.

I have updated all packages depending on xarray-datatree to use 
python3-xarray (>=2024.10).

Please let me know if you see any issue in doing it.


kind regards
