sf org sandbox resume --json needs to return sufficient information to log in

[RupertBarrow]

The information returned by sf org sandbox resume and sf org sandbox resume --json are not consistent :

% sf org sandbox resume --name INT -o xxx

=== Sandbox Org Create/Refresh Status

 Field         Value                        
 ───────────── ──────────────────────────── 
 Id            xxx           
 SandboxName   INT                          
 Status        Completed                    
 LicenseType   DEVELOPER

The sandbox org create/refresh was successful.
The username for the sandbox is user@domain.com.int.
You can open the org by running "sf org open -o user@domain.com.int"

whereas

% sf org sandbox resume --name INT -o xxx --json
{
  "status": 0,
  "result": {
    "attributes": {
      "type": "SandboxProcess",
      "url": "/services/data/v60.0/tooling/sobjects/SandboxProcess/xxx"
    },
    "Id": "xxx",
    "Status": "Completed",
    "SandboxName": "INT",
    "SandboxInfoId": "xxx",
    "LicenseType": "DEVELOPER",
    "CreatedDate": "2024-05-20T17:43:43.000+0000",
    "CopyProgress": 100,
    "SandboxOrganization": "xxx",
    "SourceId": null,
    "Description": "xxx",
    "EndDate": "2024-05-20T18:41:24.000+0000"
  },
  "warnings": []
}

The --json does not return sufficient information to log in to the org.

We need --json to return the username (as it is displayed in the interactive mode), or at least the sandbox alias
