### Godot version

4.0.beta13 (caacade56)

### System information

Windows 10

### Issue description

Seems like this was missed in #62011 and #70540. `@export_multiline` should also support the PackedStringArray datatype on top of Array[String] and Dictionary, but it doesn't, instead giving the error `"@export_multiline" annotation requires a variable of type "String" but type "PackedStringArray" was given instead.`

### Steps to reproduce

Create a PackedStringArray with the `@export_multiline` annotation.
```gdscript
@export_multiline var npc_dialog: PackedStringArray
```
