itertuples doesn't respect name parameter

[davetapley]

Describe the bug

Per the docs name is:

The name of the returned namedtuples or None to return regular tuples.

But this repo only gives:

pandas-stubs/pandas-stubs/core/frame.pyi

Lines 249 to 251 in 56eafc1

	def itertuples(
	self, index: _bool = ..., name: _str | None = ...
	) -> Iterable[_PandasNamedTuple]: ...

Where:

pandas-stubs/pandas-stubs/core/frame.pyi

Lines 2276 to 2277 in 56eafc1

	class _PandasNamedTuple(tuple[Any, ...]):
	def __getattr__(self, field: str) -> Scalar: ...

To Reproduce

df = DataFrame({'num_legs': [4, 2], 'num_wings': [0, 2]},
               index=['dog', 'hawk'])
tuples: Iterable[tuple[int, int]] = df.itertuples(name=None)

Pyright:

Expression of type "Iterable[_PandasNamedTuple]" cannot be assigned to declared type "Iterable[tuple[int, int]]"
  "Iterable[_PandasNamedTuple]" is incompatible with "Iterable[tuple[int, int]]"
    Type parameter "_T_co@Iterable" is covariant, but "_PandasNamedTuple" is not a subtype of "tuple[int, int]"
      "_PandasNamedTuple" is incompatible with "tuple[int, int]"
        Tuple size mismatch; expected 2 but received indeterminatePylance[reportGeneralTypeIssues](https://github.com/microsoft/pyright/blob/main/docs/configuration.md#reportGeneralTypeIssues)

Please complete the following information:

• OS: Ubuntu 20.04.6 LTS
• python 3.11.4
• pyright v1.1.347
• pandas-stubs 2.1.4.231227

Additional context

Also notable that the actual returned type is either map or zip for name Pandas or None respectively.

Thanks for the report. I think we need to add an @overload on itertuples() for when name = None that returns a tuple[Any, ...]

@Dr-Irv I can do a PR, I need to finish #818 anyway :)
