### 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

N/A
push_text("Await ");
	print_expression(p_await->to_await);
}
void GDScriptParser::TreePrinter::print_binary_op(BinaryOpNode *p_binary_op) {
	
	push_text("(");
	print_expression(p_binary_op->left_operand);
	switch (p_binary_op->operation) {
		case BinaryOpNode::OP_ADDITION:
			push_text(" + ");
			break;
		case BinaryOpNode::OP_SUBTRACTION:
			push_text(" - ");
			break;
		case BinaryOpNode::OP_MULTIPLICATION:
			push_text(" * ");
			break;
