Disabling Kafka health check is not working.

Describe the bug Disabling Kafka health check by configuring quarkus.kafka.health.enabled=false is not working as expected. Expected behavior On configuring quarkus.kafka.health.enabled=false Kafka health must not run

Actual behavior It runs the health even after setting quarkus.kafka.health.enabled=false. It returns below response

HTTP/1.1 503 Service Unavailable
content-length: 245
content-type: application/json; charset=UTF-8

{
    "checks": [
        {
            "data": {
                "kafka-connector": "[KO]"
            },
            "name": "SmallRye Reactive Messaging - readiness check",
            "status": "DOWN"
        }
    ],
    "status": "DOWN"
}

To Reproduce

Link to a small reproducer (preferably a Maven project if the issue is not Gradle-specific).

Or attach an archive containing the reproducer to the issue.

Steps to reproduce the behavior:

1. Create Quarkus application
2. Add quarkus-smallrye-reactive-messaging-kafka , quarkus-smallrye-health dependencies
3. Add quarkus.kafka.health.enabled=false
4. Call health REST endpoint for example http localhost:8080/q/health/ready

Configuration

# Add your application.properties here, if applicable.
quarkus.vertx.prefer-native-transport=true
quarkus.http.so-reuse-port=true
quarkus.http.tcp-quick-ack=true
quarkus.http.tcp-cork=true
quarkus.http.tcp-fast-open=true

## disable kafka health check
quarkus.kafka.health.enabled=false

## Logs
quarkus.log.level=DEBUG

## openapi configuration
mp.openapi.extensions.smallrye.openapi=3.0.3

## Http client  configuration
mp.messaging.outgoing.metrics.connector=smallrye-http
mp.messaging.outgoing.metrics.method=POST

There are two levels of health checks: the one coming from the Quarkus Kafka extension and the one comings from Reactive Messaging.

To disable the checks on reactive messaging, use:

mp.messaging.outgoing.metrics.health-enabled=false

If you have multiple channels, and want to disable them globally, use:

mp.messaging.connector.smallrye-kafka.health-enabled=false

Closing - please reopen if it still happens. A reproducer would be really nice.
