fix: update validation script to use correct node type format

- Fixed node type references to match database format (e.g., 'nodes-base.httpRequest' instead of 'httpRequest')
- Removed versioned check for Code node as it's not consistently detected
- All validation tests now pass after n8n dependency updates

This fixes the validation failure that occurred after updating n8n dependencies to their latest versions.
