feat: Update test snapshots for single repo update

The code changes in PR #2378 ensure that helm repo update is only run once
before building dependencies. This requires updating test snapshots to include
the 'Updating repo' output that now appears before 'Building dependency' messages.

Updated snapshots:
- chart_need/output.yaml
- chart_need_enable_live_output/output.yaml
- release_template_inheritance/output.yaml
- environments_releases_without_same_yaml_part/output.yaml
- environment_missing_in_subhelmfile/output.yaml
- pr_560/output.yaml
- environments_values_gotmpl_with_environment_name/output.yaml
- postrenderer/output.yaml (fixed YAML structure)
- oci_need/output.yaml
