PyQt6 Enum implcit conversion

[Julien Cabieces]

The same example is working in pure python

---
class MyEnum(IntEnum):
   VALA=0
   VALB=1
   VALC=2

def printEnum(an_enum):
   if an_enum == MyEnum.VALA:
      print("VALA")
   else:
      print("others")

printEnum(1)
others
---

It makes sense to me for an IntEnum to be able to convert from/to an
integer, no?
