For .blend files, the rightclick menu entry should display 'New/..' as usual, but it instead displays 'Show in File System' (functionality is not impacted)

### Steps to reproduce

Have a .blend file and some other asset (or a folder), rightclick both, notice the difference in the 'new' submenu labeling.

### Minimal reproduction project

Any blend file and any other asset will do, but if necessary i can upload random stuff.
TreeItem *selected = tree->get_selected();
	if (selected) {
		String file_path = selected->get_metadata(0);
		TreeItem *parent = selected->get_parent();
		bool is_favorite = parent != nullptr && parent->get_metadata(0) == "Favorites";
		if ((!is_favorite && file_path.ends_with("/")) || file_path == "Favorites") {
			bool collapsed = selected->is_collapsed();
			selected->set_collapsed(!collapsed);
		} else {
			_select_file(file_path, is_favorite && !file_path.ends_with("/"));
		}
	}
