Micrometer: Router policy should be disabled by default (to be consistent with Camel)

### Bug description

As you can see in Camel [documentation](https://camel.apache.org/components/3.20.x/micrometer-component.html#_using_micrometer_route_policy_factory), RoutePolicyFactory is not enabled by default. CQ should be consistent with this behavior and change default value for property `camel.metrics.enableRoutePolicy` to `false` ([code](https://github.com/apache/camel-quarkus/blob/main/extensions/micrometer/runtime/src/main/java/org/apache/camel/quarkus/component/micrometer/CamelMicrometerConfig.java#L30))
