fix: skip volume fields for serverless templates, add tests field to hub release

- serverless template creation via REST fails because the api rejects
  volumeInGb on serverless templates even when set to 0; skip sending
  volume fields when --serverless is set
- include tests field in hub release get response so agents can use
  the pre-built test payloads to call deployed endpoints
