Upload command now returns full JSON response from Appetize

This makes it easier for other command-line tools to use the data in the response payload.

For example:

{"publicKey":"REDACTED","privateKey":"REDACTED","updated":"2021-09-09T19:09:05.941Z","email":"REDACTED","platform":"android","versionCode":1,"created":"2021-09-09T19:09:05.941Z","architectures":[],"appPermissions":{},"publicURL":"REDACTED","appURL":"REDACTED","manageURL":"REDACTED"}
