When using aws-load-balancer-controller, it is useful to pass annotations in the Service ( https://github.com/trinodb/charts/blob/trino-0.19.0/charts/trino/templates/service.yaml ) to denote what properties the load balancer could have.

Proposed solution: From https://github.com/trinodb/charts/blob/trino-0.19.0/charts/trino/values.yaml#L226

service:
  type: ClusterIP
  port: 8080
  annotations: {} # <--------- this field is new

From https://github.com/trinodb/charts/blob/trino-0.19.0/charts/trino/templates/service.yaml

  metadata:
  name: {{ template "trino.fullname" . }}
  labels:
    app: {{ template "trino.name" . }}
    chart: {{ template "trino.chart" . }}
    release: {{ .Release.Name }}
    heritage: {{ .Release.Service }}

I could make a pull request if you'd like.
