Description of the bug

I have methods defined with @typing.overload but they are not showing up in the generated docs. Other methods show up fine, but not the overload ones. There are no warnings. I am using the insiders version of mkdocstring-python and griffe

My docs are generated from definitions like this in my pyi file:

@typing.overload
def add_column(
    self, name: str, type: types.DataType, format: formats.DataFormat
) -> None:
    """
    Add a new column to the data container
    """

@typing.overload
def add_column(self, name: str, type: types.HumanType) -> None:
    """
    Add a new column to the data container
    """

@typing.overload
def add_column(self, name: str, type: types.DataType) -> None:
    """
    Add a new column to the data container
    """

NOTE: There is not any backing .py file because this is a wrapper around a c++ python module. So the mkdocstrings generation is purely going against the .pyi files.

To Reproduce

.pyi file with the definitions above

Expected behavior

Expect the overloaded methods to show in the docs
