Updated python-django/python-asgiref packages fix security vulnerability

The {% debug %} template tag didn’t properly encode the current context posing an XSS attack vector (CVE-2022-22818). Passing certain inputs to multipart forms could result in an infinite loop when parsing files resulting in a denial of service (CVE-2022-23833). The python-django update necessitated a version update to python-asgiref as well.
