/**
 * If a JAX-RS resource uses something like @QueryParam, @HeaderParam or the like in a constructor parameter,
 * then we need to make sure that Arc doesn't create a bean for it automatically (as it will fail validation because
 * there is no way to pass the parameter).
 * For these resources we add {@link jakarta.enterprise.inject.Vetoed}, and we generate custom CDI producers under the hood
 * in {@code io.quarkus.resteasy.reactive.server.deployment.CustomResourceProducersGenerator#generate}.
