TLS/HTTPS sink is unable to receive events

Running with TLS, on the `IntegrationSink` there is a timeout on sending events to the Sink. Here is a log for a "source dispatcher", in a test suite:

```

Start by comparing the sender configuration in eventshub/sender/sender.go with the generated IntegrationSink Deployment and its container port. Inspect camel/sink.yaml and log-sink.kamelet.yaml, then reproduce the TLS test while checking whether the HTTPS endpoint is reachable and serving TLS. Done means the TLS-enabled IntegrationSink accepts events without the sender timing out.
