fix(n8n): restructure version handling for nix-update compatibility
- Store version without 'n8n@' prefix (e.g., '2.8.3' not 'n8n@2.8.3')
- Construct tag with prefix: tag = "n8n@${version}"
- Update to version 2.8.3 with correct hashes

This allows nix-update to work correctly with the custom update.sh
script that strips the 'n8n@' prefix from GitHub release tags.
