### System information

Windows 10

### Issue description

Returned Array value isn't converted to Packed*Array

### Steps to reproduce

```
var string_array: PackedStringArray = ["test"] # valid
var int_array: PackedInt32Array = [3] # valid

func get_packed_string_array() -> PackedStringArray:
	return ["test"] #error


func get_packed_int_array() -> PackedInt32Array:
	return [3] #error
```

Line 8:Cannot return value of type "Array" because the function return type is "PackedStringArray".
Line 12:Cannot return value of type "Array" because the function return type is "PackedInt32Array".
