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.
Vector<int> selected_id = files->get_selected_items();
	Vector<String> selected;
	for (int i = 0; i < selected_id.size(); i++) {
		selected.push_back(files->get_item_metadata(selected_id[i]));
	}
	_file_option(p_option, selected);
}
void FileSystemDock::_file_option(int p_option, const Vector<String> &p_selected) {
	
	switch (p_option) {
		case FILE_SHOW_IN_EXPLORER: {
			
			String fpath = path;
			if (path == "Favorites") {
				fpath = p_selected[0];
			}
			if (!fpath.ends_with("/")) {
				fpath = fpath.get_base_dir();
			}
			String dir = ProjectSettings::get_singleton()->globalize_path(fpath);
			OS::get_singleton()->shell_open(String("file://") + dir);
		} break;
		case FILE_OPEN_EXTERNAL: {
			String fpath = path;
			if (path == "Favorites") {
				fpath = p_selected[0];
			}
			String file = ProjectSettings::get_singleton()->globalize_path(fpath);
			String resource_type = ResourceLoader::get_resource_type(fpath);
			String external_program;
