[dj-rest-auth] CustomRegisterSerializer

이메일 인증을 하기 위해 dj-rest-auth를 사용하던 중 nickname 필드를 추가해야 해서
https://www.rootstrap.com/blog/registration-and-authentication-in-django-apps-with-dj-rest-auth 를 참고로 시리얼라이저와 ConfirmRegisterView 를 커스텀했는데 막상 dj-rest-auth/registration/ 으로 접속해보니 필드가 그대로였다.

알고보니 views.py 의 ConfirmRegisterView 에도 커스텀한 시리얼라이저를 사용하겠다는 것을 명시해줘야 했다는 것
