Response to MS Teams

### Jenkins and plugins versions report

Environment

```text
Paste the output here
```

### What Operating System are you using (both controller, and any agents involved in the problem)?

Jenkins - Windows

### Reproduction steps

1. send an outgoing webhook from teams using @nameofoutgoinghook somedata
2. jenkins gets the webhook and starts the build
3. Teams shows "Sorry, there was a problem encountered with your request"
4. jenkins completes the build.

### Expected Results

I'd expect to be able to specify a response to teams or at lease have the most basic response sent back to teams then we can use the jenkins connector for the build status.

{
"type": "message",
"text": "Jenkins is processing your request!"
}

### Actual Results

The teams-webhook-trigger just sends a 200 response with empty content {}
