bug: Problem when rendering ENUM value

[gadsc]

Description of the bug

The ENUM render isn't rendering the ENUM name in the value.

To Reproduce

1. Create an enum:

class MyEnum(Enum):
    """Just a ENUM example"""
    MY_VALUE_1 = 1
    MY_VALUE_2 = 2

2. Reference the ENUM value in a field:

MY_FIELD = MyEnum.MY_VALUE_1.value

MY_FIELD_ARRAY = [ MyEnum.MY_VALUE_1.value, MyEnum.MY_VALUE_2.value ]

3. Generate the doc.

Generated doc:

Expected behavior

For ENUM values the ENUM name/full qualified name helps to gather context, it should render at least the ENUM name in the value, like MyEnum.MY_VALUE_1.value, the constant MY_VALUE_1.value or the full qualified name my_module.MyEnum.MY_VALUE_1.value.

Enum values should now always render the enum instance name too.
