Add support of javadoc syntax

[dgroup]

Javadoc comment format for java language has the following format

/**
 * This is the user.
 * @author someone
 * @since 0.0.0
 */
public class User {
   
}
```

Thanks for this. I think we need to make a change elsewhere to support this. At the moment, the title has to be on the same line as the opening tag, so we need to update the regex and add a test. If I get chance I'll take a look.

Acutally, I don't think any regex changes are required. There are already TODOs in the tests where the opening tag and title are on different lines. I think we just need to add a test for this and we're all good.
