[AWS S3 Source] Unuspported ignoreBody option

[acolombier]

The ignoreBody doesn't seem to have any effect. Here is a minimal reproduction steps:

apiVersion: sources.knative.dev/v1alpha1
kind: IntegrationSource
metadata:
  name: integration-source-aws-s3
spec:
  aws:
    s3:
      arn: "my-bucket"
      ignoreBody: true
      region: eu-west-1
    auth:
      secret:
        ref:
          name: "aws-s3-secret"
  sink:
    ref:
      apiVersion: eventing.knative.dev/v1
      kind: Broker
      name: default

Expect

Events without the S3 object content as message

Actuall

Same than without the option, the S3 object content is used as message
