Release the package with Django 3.2 support

[Jawayria]

Hey, we are working on upgrading edX codebase to Django 3.2. This package is being used in the codebase but it isn't yet released with Django 3.2 support. Kindly consider releasing it with Django 3.2 support.
Thanks

It does have Django 3.2 support, it's just not currently listed on the docs.
