task: Use Webship addresses for the Nightwatch test accounts

Problem/Motivation

nightwatch.conf.js at the root of the Webship Project template still carries a test account e-mail address on a domain that is not Webship's: the Content admin account, line 34 of the file on 12.0.x (the same line in the 12.0.3 release). The admin and Authenticated user accounts in the file already use @webship.co.

The template is published on drupal.org and mirrored to github.com/webship/webship-project, so the leftover shows up in public code searches. The Nightwatch configuration itself is no longer the project's test runner (the webship-js suite is, see #3636722), but the file ships with every release.

Steps to reproduce

1. Open nightwatch.conf.js on 12.0.x.
2. Read the email values of the test accounts under globals.users.

Proposed resolution

Use @webship.co addresses for every Nightwatch test account in nightwatch.conf.js (same local parts, Webship's domain), and change nothing else in the file. Today that is the Content admin account on line 34 only. One commit, one merge request against 12.0.x.
