help request: `opentelemetry` input does not update the `fluent-bit` service

Bắt đầu bằng cách theo dõi cách các tài nguyên OpenTelemetry Input và ClusterInput cập nhật pod và Service của Fluent Bit, đồng thời so sánh quy trình đó với việc cập nhật thành công secret fluent-bit-config. Tái hiện sự cố bằng chart fluent-operator và xác minh rằng việc thêm một input opentelemetry sẽ expose port 4318 trên cả pod và Service.

Describe the issue

Adding opentelemetry input/clusterinput resources neither triggers addition of 4318 port to existing fluent-bit service, nor creation of a new one. The fluentbit-config k8s secret is updated successfully:
