### Issue description

When you use batch rename you can ask him to rename to invalid node names. it won't raise any warning nor error it will just rename to a valid node names without informing you of the change. For comparison with simple renames this is shown as warning

### Steps to reproduce

1. create a root Node and two Node children
2. select the two children
3. Batch rename the `e` to `%`
4. See that childrens have been renamed to `Nod_` and `Nod_2` without warning 

### Minimal reproduction project

N/A
if (!can_rename) {
		return Variant(); //not editable tree
	}
	if (tree->get_button_id_at_position(p_point) != -1) {
		return Variant(); //dragging from button
	}
	Vector<Node *> selected_nodes;
	Vector<Ref<Texture2D>> icons;
	TreeItem *next = tree->get_next_selected(nullptr);
	while (next) {
		NodePath np = next->get_metadata(0);
		Node *n = get_node(np);
		if (n) {
			// O
			if (!n->get_owner() || n->get_owner() == get_scene_node() || n->get_owner()->get_scene_file_path().is_empty()) {
				selected_nodes.push_back(n);
				icons.push_back(next->get_icon(0));
			}
		}
		next = tree->get_next_selected(next);
	}
	if (selected_nodes.is_empty()) {
		return Variant();
