Incorrect links to django-filters in web docs

[MarcinWronecki]

• What is the current behavior?
  Links in web docs (https://docs.graphene-python.org/projects/django/en/latest/filtering/) incorrectly refer to the master branch of django-filter instead of main/ stable or latest. Code base links are correct (but one used main and the second one stable name, however, it reference to the same docs on django-filter), so web docs should have the same links as in the code.

• What is the expected behavior?

• Links should refer to existing django-filter dosc
