Docs: dataclasses: wrong error documented #106107
Description
Documentation
Data Classes - Mutable default values says in the second blockquote
x: list = [] # This code raises **ValueError**
but in the explanantion (two paragraphs down) it notes:
Instead, the dataclass decorator will raise a TypeError if it detects an unhashable default parameter.
This is inconsistent, in fact a ValueError is raised, cf. https://github.com/python/cpython/blob/e8e59ee474869e7c02e7cae3815c9c2183671b21/Lib/dataclasses.py#L848C1-L853C1
