new rule - ban subtyping dataclass with `order=True`

https://docs.astral.sh/ty/reference/rules/#subclass-of-dataclass-with-order

```py
from dataclasses import dataclass

@dataclass(order=True)
class Parent:
value: int

class Child(Parent): # Ty emits a warning here
pass

# At runtime, this raises TypeError:
Child(1) < Parent(2)
```
