Rollout jupyterhub-groups-exporter for all hubs with manage_groups feature

[jnywong]

Context

Following the rollout manage_groups feature in #5805, we need to verify that the feature is working as intended before rolling out the jupyterhub-groups-exporter. We also need to update the code base to remove legacy code pertaining to upstream PR upstream PR. See also related issue #5314.

Tasklist

• Verify that all GitHub authenticated hubs have manage_groups working as expected. This means that users that have logged out and in again are populating the groups table in the JH database as expected.
• Rollout jupyerhub-groups-exporter to Earthscope prod hub
• Remove legacy code pertaining to upstream PR from jupyerhub.hub.extraConfigin helm-charts/basehub/values.yaml in the test hub.
• Validate that the legacy code is indeed no longer needed after removal and that the hub behaves as expected
• Repeat the above for all eligible hubs
• Consolidate config change into basehub chart values Update basehub chart values to enable jupyterhub-groups-exporter service #6032

I believe this issue #5314 is also related and think that it tracks the last bullet point of the task list I believe.
