Authentication not working with secure openapi operation

When invoking a request to a secure openapi operation the request receives and authentication error even though the authentication details are configured correctly in the application.properties file.

The scenario is that I am trying to access the github.com /user/emails path which requires the user to be authenticated.

I have created a personal access token (PAT) that gives me access to do `/user/emails`. I can call that using curl from my macbook with the PAT specified  but when I try and invoke that from within a sw.yaml, it always seems to give me an authentication error.

```
I have specified the properties in the application.properties file:
```
org.kogito.openapi.client.api.github.com.username=<my usrid>
org.kogito.openapi.client.api.github.com.password=<my PAT>
```
but this still seems to say that the request is unauthorised.
