### 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
```

### Minimal reproduction project

const Dictionary drag_data = p_data;
	if (!drag_data.has("type")) {
		return false;
	}
	if (String(drag_data["type"]) != "files") {
		return false;
	}
	const Vector<String> filesPaths = drag_data["files"];
	if (filesPaths.size() == 0) {
		return false;
	}
	for (const String &extension : extensions) {
		if (filesPaths[0].ends_with(extension.substr(1, extension.size() - 1))) {
			return true;
		}
	}
	return false;
