str/repr mixup in StringEnum?

Lines 78 to 83 in 630116c

	class StringEnum(str, Enum):
	"""Base :class:`enum.Enum` class for string enums that will serialize as the string
	value."""
	def __repr__(self) -> str:
	return str(self.value)

Is it intentional to return str(self.value) instead of repr(self.value) here?

Yeah that seems fine to switch it to repr not sure if it would ever make a difference since by definition the value will always be a string, but I don't see a downside so please open a PR if you feel it's an improvement.
