Docs: dataclasses: wrong error documented

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

Yeah, there should be a ValueError.
Would you like to send a PR?
