hotfix: fix 500 error of "taggit_autosuggest-list" (#254)

```
django.urls.exceptions.NoReverseMatch: Reverse for 'taggit_autosuggest-list' not found. 'taggit_autosuggest-list' is not a valid view function or pattern name.
```

The problem is caused by using url, but Django 4 app should use re_path.
