When I was updating the URLs, I kept the regex that we were previously
using for the password_reset_confirm URL. Unfortunately, it looks like
Django has updated their token generation to create tokens that are
longer than the 20 characters that our old URL handled, resulting in a
NoReverseMatch. The upstream URLs inside the django.contrib.auth app
now just use reset/<uidb64>/<token>/, so I've updated ours to match.

Went through the password reset process and saw that I didn't get URL
lookup errors anymore.
