camel-quarkus-examples/aws-lambda does not run

### Description

The aws-lambda example does not run in dev mode because the dev-ui console is taking the 8080 port. This is seemingly not an issue with plain quarkus http server apps, but it seems the lambda mock server does not play well with the dev-ui (assuming it's based on vertx features).

It'd seem to me this should be documented _somewhere_.

Reproduced by
```bash
git clone git@github.com:apache/camel-quarkus-examples.git
cd camel-quarkus-examples/aws-lambda/
mvn quarkus:dev
```

results in

```

Start in the camel-quarkus-examples/aws-lambda example and reproduce the failure with mvn quarkus:dev. Document why the Lambda mock server and Dev UI conflict on port 8080, along with the supported way to run the example; done means a newcomer can follow the guidance and start the example in dev mode.
