Description of problem:

PR #1657 "feature: adding orchestrator to GA" incorrectly sets support.level: production (and support: production for metadata files) instead of support.level: generally-available. The codebase standard for Generally Available plugins is to use generally-available as evidenced by 28 other plugin configurations.
Affected files:

• catalog-entities/marketplace/plugins/orchestrator-scaffolder-actions.yaml
• catalog-entities/marketplace/plugins/orchestrator.yaml
• workspaces/orchestrator/metadata/redhat-backstage-plugin-orchestrator-backend.yaml
• workspaces/orchestrator/metadata/redhat-backstage-plugin-orchestrator-form-widgets.yaml

support:
  provider: Red Hat
  level: generally-available  # CORRECT
