Update Reference Architecture docs when GitLab pages transitioned to object storage
Problem to solve
Pages is planned to move to Object Storage from NFS (epic: &3901 (closed)), thus we need to update Reference Architecture documentation:
- Configure NFS section: Remove the guidance about Pages and NFS
- Configure the object storage section: update Object storage type table with the Pages option, related to !45279 (merged)
Other links/references
- Transition GitLab pages to object storage instead of NFS epic: &3901 (closed)
