State explicitly to remove the gitlab_repmgr database

See merge request gitlab-org/gitlab!54051

In the learn gitlab experiment we want to link to issues that are only

actions require a trial.
With this MR, we use the ultimate template when the experiment is active
and also update the issue IDs to link to the right issue to get more
information.

See merge request gitlab-org/gitlab!55124
