Description
Issue description
arithmetic isn't working for scoped enums.
Reproducible example code
If I have
enum_<ScopedEnum>(m, "ScopedEnum", arithmetic{})
.value("Value1", ScopedEnum::Value1)
...
then in python
ScopedEnum.Value1 | ScopedEnum.Value1
it throws error unsupported operand type(s) for |: 'int' and 'ScopedEnum'

Research direction
Start with the reproducible enum_(..., arithmetic{}) example and trace pybind11's scoped-enum arithmetic handling; the issue names no file or test. Done means ScopedEnum.Value1 | ScopedEnum.Value1 no longer raises the reported operand-type error, with regression coverage for this example.
