Geo DR documentation: Make it more obvious yum remove gitlab-ee is only for CentOS
In https://docs.gitlab.com/ee/gitlab-geo/disaster-recovery.html#step-2-permanently-disable-the-primary, the text looks like yum remove gitlab-ee
should be copied and pasted with the rest of the steps.
I think it would be helpful to make it clearer visually that this is a special command only for CentOS. Also, does removing the package apply to Ubuntu etc.?
