Geo: Update Geo container registry replication settings for Helm Charts

Nick Westburyrequested to merge
geo_container_replication into main

What does this MR do?

This code change makes three improvements to GitLab's geo-replication configuration:

  1. Fixes container registry setup: The logic for enabling container registry replication has been restructured to reflect recent chantes in the Charts documentation.

  2. Fixes a compatibility issue: Updates how the system retrieves server names to use a newer, more reliable method. This ensures the configuration works properly with current versions of the underlying automation tools.

These changes improve the reliability and maintainability of GitLab's geo-replication feature, which allows organizations to have synchronized GitLab instances across multiple geographic locations for better performance and disaster recovery.
