providing_args deprecation warning Django 3.1

[deeprave]

Describe the bug
Django 3.1 issues this deprecation warning:

..../simple_history/signals.py:4: RemovedInDjango40Warning: The providing_args argument is deprecated. As it is purely documentational, it has no replacement. If you rely on this argument as documentation, you can move the text to a code comment or docstring.
    pre_create_historical_record = django.dispatch.Signal(

... and same again on line 14 for post_create_historical_record.

To Reproduce
Steps to reproduce the behavior:

1. run the addon using Django 3.1
2. run some test or action which triggers the pre and/or post signal
3. See deprecation warning

Expected behavior
No deprecation warning :-)

Environment (please complete the following information):

• OS: MacOS 10.14.6
• Browser N/A (I see this in pytest output)
• Django Simple History Version: 2.11.0
• Django Version: 3.1.2
• Database Version: postgresql 12.4

Additional context
Should be reproducible anywhere.

This was already fixed in #702

We're planning on cutting release within the next week or so.
