[Feature request] Annotation for referring to superclass

I'm trying to add annotations to classic, but encounter a few problems when doing so.

For example, the super field refers to the superclass. If I were to annotate super like this

---@class Object
---@field protected super Object

then subclasses will have a super field, but it will always refer to Object, instead of their superclass. The best solution I can come up with the current implementation is to set the super field each time a class is created.

---@class Animal : Object
---@field super Object
local Animal = Object:extend()

---@class Bird : Animal
---@field super Animal
local Bird = Object:extend()

This is a repetition of steps, which tells me DRY. I suggest something like a super annotation, which always refers to the superclass relative to which class it is being used.

---@class Object
---@field protected super super

---@class Animal : Object
local Animal = Object:extend()
-- Animal.super refers to Object

---@class Bird: Object
local Bird = Animal:extend()
-- Bird.super refers to Animal

Beginne mit der Durchsicht der im Issue referenzierten Annotationsbeispiele und des Vererbungsmodells von classic.lua. Ermittle, wo Annotationen für Klassenfelder aufgelöst werden, und definiere, wie sich eine Annotation relativ zur Oberklasse für Object, Animal und Bird verhalten soll; im Issue werden keine LuaLS-Dateien oder Tests genannt, daher müssen die Abschlusskriterien vor der Implementierung festgelegt werden.
