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.
if (file_list_display_mode == FILE_LIST_DISPLAY_THUMBNAILS && p_path.get_base_dir() == path && searched_string.length() == 0 && file_list_vb->is_visible_in_tree()) {
		for (int i = 0; i < files->get_item_count(); i++) {
			if (files->get_item_metadata(i) == p_path) {
				
				Array udata;
				udata.resize(2);
				udata[0] = i;
				udata[1] = files->get_item_text(i);
				EditorResourcePreview::get_singleton()->queue_resource_preview(p_path, this, "_file_list_thumbnail_done", udata);
				break;
			}
		}
