django-summernote breaks after upgrading to Django 3

After upgrading my app to Django 3 I get the following error:

Traceback (most recent call last):
  File "manage.py", line 23, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/local/lib/python3.7/site-packages/django/core/management/__init__.py", line 401, in execute_from_command_line

    from django.contrib.staticfiles.templatetags.staticfiles import static
ModuleNotFoundError: No module named 'django.contrib.staticfiles.templatetags'

regarding to https://docs.djangoproject.com/en/dev/internals/deprecation/ that module was removed.

After investigation of the Django sources replacing should be easy:

# django 2.x django\contrib\staticfiles\templatetags\staticfiles.py
def static(path):
    warnings.warn(
        'django.contrib.staticfiles.templatetags.static() is deprecated in '
        'favor of django.templatetags.static.static().',
        RemovedInDjango30Warning,
        stacklevel=2,
    )
    return _static(path)

I think the problem may be that the package at https://pypi.org/project/django-summernote/ is outdated. It dates from January 2019. As the problem ist already fixed in the summernote sources only a new package needs to get published.
