gdscript syntax highlighter colors some typed variable names with the same color as the type

[radishes]

Tested versions

bb1006b (master branch from today.) I've noticed this since 4.3 dev began.

System information

Windows 10

Issue description

If strong typing is used in a list of parameters in a function definition, variable names past the first will be colored with the same color as the types.

In this screenshot, the coloration of another_argument by the syntax highlighter seems incorrect. In past versions of Godot, another_argument would have been the same color as an_argument.

Steps to reproduce

Create a gdscript function which accepts two or more parameters which are strongly typed.

Minimal reproduction project (MRP)

func my_func(an_argument:int, another_argument:Vector2):
	pass

Probably related to #85812 as well. Fixed by the same PR.
