What steps will reproduce the bug?

1. Update listeners.extraListeners with more then one custom listener:

   listeners:
     extraListeners:
      - name: CUSTOM
        containerPort: 9097
        protocol: SASL_PLAINTEXT
        sslClientAuth: ""
      - name: CUSTOM2
        containerPort: 4097
        protocol: SASL_PLAINTEXT
        sslClientAuth: ""

2. Run helm template

What is the expected behavior?

Statefulset would have in ports

            - name: custom
              containerPort: 9097
            - name: custom2
              containerPort: 4097

What do you see instead?

Statefulset would have in ports

            - name: custom
              containerPort: 9097- name: custom2
              containerPort: 4097
