Add an option 'use_redirect_back_or_to_by_rails' to avoid definition …

…conflicts

Fix: Sorcery#296

Rails 7 released a new method called `redirect_back_or_to` as a replacement for `redirect_back`.
That may conflicts with the method by the same name defined by Sorcery.

This commit adds an option to set whether to use `redirect_back_or_to` defined by Rails 7, and
the method `redirect_to_before_login_path` as an alternative to sorcery's `redirect_back_or_to.
