xarray-datatree 0.0.14 failure with xarray=2024.10.0

### Solution to issue cannot be found in the documentation.

- [x] I checked the documentation.

### Issue

Current versions of `xarray-datatree` and `xarray` seem to not be compatible.

```
$ python -c "import datatree"
Traceback (most recent call last):
File "", line 1, in
File "/opt/miniconda3/envs/prod/lib/python3.11/site-packages/datatree/__init__.py", line 2, in
from .datatree import DataTree

ImportError: cannot import name 'HybridMappingProxy' from 'xarray.core.utils' (/opt/miniconda3/envs/prod/lib/python3.11/site-packages/xarray/core/utils.py)
```

[this package was merged into xarray 2024.10.0 ?](https://github.com/pydata/xarray/issues/8572)

Reproduce the failure with xarray-datatree 0.0.14 and xarray 2024.10.0 using the reported `python -c "import datatree"` command. Review the package metadata and the linked upstream xarray issue to determine the compatible dependency declaration; done means the package environment resolves and `import datatree` succeeds.
