Regression on master: dict.get(default=None) gives 'no overload matches argument types'

[intgr]

Bug Report

After the latest sync from typeshed (commit 4996d57, PR #11600), this valid code is highlighted as error by mypy:

def foo(vars: dict[str, str]):
    val = vars.get("fqdn", default=None)
    reveal_type(val)

Result before:

_local/dictget.py:3: note: Revealed type is "Union[builtins.str, None]"

Result after:

_local/dictget.py:2: error: No overload variant of "get" of "Mapping" matches argument types "str", "None"
_local/dictget.py:2: note: Possible overload variants:
_local/dictget.py:2: note:     def get(self, key: str) -> Optional[str]
_local/dictget.py:2: note:     def [_T] get(self, str, Union[str, _T]) -> Union[str, _T]
_local/dictget.py:3: note: Revealed type is "Any"

Caused by changes to the Mapping class in mypy/typeshed/stdlib/typing.pyi

-    def get(self, key: _KT, default: _VT_co | _T) -> _VT_co | _T: ...
+    def get(self, __key: _KT, __default: _VT_co | _T) -> _VT_co | _T: ...

Doh. My bad, it dict.get() does not support keyword arguments, the original code worked because it was using QueryDict from Django. Sorry for the noise.

So I suppose this should be solved in django-stubs instead.
