'admin_static' deprecated in Django 2.1 and removed since 3.0

[ivarsg]

With admin_static in template, trying to export form submissions will end with failure when running on Django>=3.0. Using static instead is a valid case, since djangocms-forms depend on django-cms>=3.0 which in turn depends on Django>=2.2 which already supports admin_static replacement to static.

You're right. I missed one!
