Fix ::ContainerRegistry::Migration.limit_gitlab_org?

🔥 Problem

::ContainerRegistry::Migration.limit_gitlab_org? is used to limit the image repositories selection to the gitlab-org namespace.

The problem is the condition that this check adds.

It will select any namespace whose path is gitlab-org. That’s a too wide scope: it will catch any intermediary namespaces (like sub groups) that are named gitlab-org.

What we want is the root namespace named gitlab-org

🚒 Solution

Fix the conditions to start with the root namespace named gitlab-org.
