While I worked on the route integration into Sulu. I had to write a few tests for depending on the RequestContext. To improve the DX I think the parameters should be possible also inside the construct directly so instead of:

```php
$requestContext = new RequestContext();
$requestContext->setParameters(['foo' => 'bar']);
$service->myMethod($requestContext);
```

I can do:

```php
$service->myMethod(new RequestContext(parameters: ['foo' => 'bar']));
```
