GitLab Shell version is incorrect on the 8.13 to 8.14 upgrade documentation

Summary

In the GitLab upgrade instructions from 8.13 to 8.14 the GitLab Shell version is 4.0.0 and it should be 4.0.3. If you use 4.0.0 you get an error during the install verification that the GitLab shell version should be 4.0.3.

The line in the GitLab shell portion is

sudo -u git -H git checkout v4.0.0

And it should be

sudo -u git -H git checkout v4.0.3

Steps to reproduce

Follow the upgrade instructions at https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/8.13-to-8.14.md

Expected behavior

8.14 seems to require GitLab Shell 4.0.3.

Actual behavior

Upgrade instructs you to upgrade to GitLab Shell 4.0.0
