In Custom Class Documentation a Function cannot return 'Variant'

[Jay-Dorcat]

Godot version

v4.1.1.stable.official [bd6af8e]

System information

Windows 10

Issue description

As said in the Title Custom Class Documentation a Function cannot return 'Variant' and will instead be shown to return void, even though Built-in Classes are shown to return 'Variant', an example would be 'Array'

Steps to reproduce

extends Node
class_name CustomClass

func VariantFunction() -> Variant:
	return 10

Now when checking the Generated Documentation it will appear like: void VariantFunction()
