rake gitlab:list_repos should list all repo types

Release notes

Problem to solve

The gitlab:list_repos rake task should list repos for all repository types but currently only lists project and wiki repositories.

This is a problem as we currently direct people to use this task as a way to move repos which would give incomplete results https://docs.gitlab.com/ee/administration/operations/moving_repositories.html#parallel-rsync-for-all-repositories-known-to-gitlab

Intended users

• Devon (DevOps Engineer)
• Sidney (Systems Administrator)
