Python 3.14.1 incompatibility

### 🐛 Describe the bug

It appears that Python 3.14.1 contains a regression that breaks torchvision's Weights dataclass. This results in error messages in the TorchGeo CI like:
```
AttributeError: 'wrapper_descriptor' object has no attribute '__annotate__'. Did you mean: '__getstate__'?
```
The culprit appears to be https://github.com/python/cpython/issues/142214. This was fixed in 3.14.2, but it may be worth marking 3.14.1 as an unsupported and incompatible version of Python.
