Maintain an official integration for Django

There are several community projects that integrate Elasticsearch with Django. Among them: - [django-elasticsearch-dsl](https://pypi.org/project/django-elasticsearch-dsl/) Last released in July 2025 - [django-elasticsearch](https://pypi.org/project/django-elasticsearch/) Last released in April 2020 - [django-elasticsearch-dsl-drf](https://pypi.org/project/django-elasticsearch-dsl-drf/) Last released in July 2022 All of these receive minimal maintenance, and only the first has been updated to work with release 9. Given the size of the Django community, we should evaluate offering an official integration.
