CE Install instructions point to EE package

Summary

The following link (https://about.gitlab.com/downloads/?version=ce) given in guides like https://docs.gitlab.com/ee/downgrade_ee_to_ce/README.html

Shows install instructions for Gitlab EE rather than for CE. That made me install EE by mistake.

Possible fixes

Make use of the version var that you already set, to show the right package name on each step.
