Istio Gateway Servers block templating does noting

Bug

Description

When configuring values for an istio gateway, specifying the below values for a new/custom server block it never templates down into the istio-controlplane package and therefore the gateway resource.

istio:
  gateways:
    public:
      servers:
      - hosts: 
        - test-tcp.bigbang.dev
        port:
          name: tls-2
          number: 1234
          protocol: TCP

Results in the following gateway configuration:

spec:
  selector:
    app: public-ingressgateway
  servers:
  - hosts:
    - '*.bigbang.dev'
    port:
      name: http
      number: 8080
      protocol: HTTP
    tls:
      httpsRedirect: true
  - hosts:
    - '*.bigbang.dev'
    port:
      name: https
      number: 8443
      protocol: HTTPS
    tls:
      credentialName: public-cert
      mode: SIMPLE
