How I've tested this PR:
Install Consul locally with the following values:

global:
  image: hashicorppreview/consul:1.17-dev
  imageK8S: YOUR_LOCALLY_BUILT_IMAGE_FROM_THIS_PR

ingressGateways:
  enabled: true
  defaults:
    replicas: 1
  gateways:
    - name: ingress-gateway
      service:
        type: ClusterIP

Running kubectl apply on the following IngressGateway configuration:

apiVersion: consul.hashicorp.com/v1alpha1
kind: IngressGateway
metadata:
  name: ingress-gateway
spec:
  defaults:
    passiveHealthCheck:
      interval: "10s"
      maxFailures: 5
      enforcingConsecutive5xx: 100
      maxEjectionPercent: 10
      baseEjectionTime: "10s"

The apply should succeed and you should be able to see the PassiveHealthCheck configured correctly in Consul:
consul config read -kind ingress-gateway -name ingress-gateway

    "Kind": "ingress-gateway",
    "Name": "ingress-gateway",
    "TLS": {
        "Enabled": false
