Remove special case treatment of Geo nodes for SSH

We removed SSH support in https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/3553,
so we no longer need the ability to show all refs for Geo nodes.

Closes #115

CHANGELOG

+v6.0.0
+  - Remove support unhiding of all references for Geo nodes
+
 v5.11.0
   - Introduce a more-complete implementation of bin/authorized_keys (!178)
