Modify Enum keyword default from its __repr__ to its __str__ by default?

[ringohoffman]

I found this while running on taichi:

class Program:
    def create_ndarray(self, layout: Layout = <Layout.NULL: 2>) -> Ndarray:
        ...

This expression could be made syntactically correct just by extracting out the __str__ repr of the enum value like:

class Program:
    def create_ndarray(self, layout: Layout = Layout.NULL) -> Ndarray:
        ...

Should we do this by default?

Actually it seems like this is already done:

pybind11-stubgen/tests/stubs/python-3.12/pybind11-master/numpy-array-use-type-var/demo/_bindings/enum.pyi

Lines 63 to 65 in adbd6a3

	def accept_defaulted_enum(
	color: ConsoleForegroundColor = ConsoleForegroundColor.None_,
	) -> None: ...

It seems like

--enum-class-locations="Layout:taichi._lib.core.taichi_python"

was the key! Should have read the error message closer!
