Add Django 3.2 to CI test matrix and remove 3.0 (#91)

* Add Django 3.2 to CI test matrix and remove 3.0

Also switches to v2 of the cache GitHub action, as well as specifies
Django version numbers in a slightly more-readable fashion and
then installs them via the "compatible release" specifier.

* Update expected HTML in form validation tests

* Updated classifiers
