revert docker env var changes (#9735)

## Purpose

In a [previous commit](https://github.com/CenterForOpenScience/osf.io/commit/dc28c21c674e5f971b8368512f1e4a4ebbdec123), we changed some docker environment variables from using `localhost` as the domain to using a loopback interface alias (`192.168.168.167`) as the domain. This inadvertently broke some functionalities locally (e.g. login). This PR reverts those changes.
