Update code order with static annotation on gdscript_styleguide.rst

[Xinart]

Update code order on gdscript_styleguide.rst
by inserting static variables and methods on the code order as a proposal

[dalexeev]

Personally, I prefer to place static members before non-static ones, so I would suggest the following order:

01. @tool, @icon, @static_unload
02. class_name
03. extends
04. ## class doc comment

05. signals
06. enums
07. constants
08. static public variables
09. static private variables
10. @export variables
11. public variables
12. private variables
13. @onready variables

14. static public methods
15. static private methods
16. optional built-in virtual _init method
17. optional built-in virtual _enter_tree() method
18. built-in virtual _ready method
19. remaining built-in virtual methods
20. public methods
21. private methods
22. subclasses

(Actually, I use a slightly different order.)

Ok currently i have been thinking of changing this part a bit differently to be better understanble and to not overweight the code order with the access modofiers beceause it makes doublons and harder to read, i'll do a litle update

I Agree with what you said beceause they should be easily findable

@AThousandShips I commited your reviews, is it fine now to merge the branch ?

[AThousandShips]

It needs an approval first

[Xinart]

Is it possible to have an approval on this to merge the branch @AThousandShips ?

[AThousandShips]

That's dalexeev's area :)

[dalexeev]

There seems to be no objection. Just a couple of minor comments. Thank you!

Suggested change

	01. ``@tool``, ``@icon``, ``@static_unload``
	01. @tool, @icon, @static_unload

Sorry, I didn't notice that the list is already inside the code block.

[dalexeev]

Suggested change

	12. ``_static_init()``
	12. _static_init()

[dalexeev]

Suggested change

	10. remaining variables
	11. @onready variables
	10. remaining regular variables
	11. @onready variables

I'm not sure how best to say "except @onready".
