var_to_bytes omits type of typed array

Issue description

@export var _e_export: Array[String]
func _ready():
    var bytes_export = var_to_bytes(_e_export)
    var var_export = bytes_to_var(bytes_export)
    _e_export = var_export # Error

This snippet of code will crash with the error Trying to assign an array of type "Array" to a variable of type "Array[String]". because var_to_bytes doesn't seem to store the type of the typed array _e_export.

Steps to reproduce

1. Create a new project
2. Create a new empty scene and place the code snippet above inside a node

Not sure whether this qualifies as a bug or not - partly because the implementation of typed arrays isn't fully complete yet and no one is currently working on it :)

But as a work-around, the following works:

extends Node
@export var _e_export: Array[String]
func _ready():
	var bytes_export = var_to_bytes(_e_export)
	var var_export = bytes_to_var(bytes_export)
	_e_export.assign(var_export) # No Error
	print(_e_export)
