Setting the same key name "`x`" in an extended `TypedDict` class as the same parameter name "`x`" gets the wrong error message saying `argument` but not `parameter`

*Notes:

• mypy test.py
• mypy 1.19.1
• Python 3.14.0

Setting the same key name "x" in an extended TypedDict class as the same parameter name "x" gets the wrong error message saying argument but not parameter as shown below:

from typing import TypedDict, Unpack

class MyDict(TypedDict):
    x: str
    y: bool

def func(x: int, **kwargs: Unpack[MyDict]): ...
# Error

error: Overlap between argument names and ** TypedDict items: "x"

So the error message should say parameter as shown below:

error: Overlap between parameter names and ** TypedDict items: "x"
