Hi.

I'm trying to apply a middleware in global to my fresh install of traefik ingress. I use the traefik chart to deploy traefik.

```auto
time="2022-06-30T14:31:16Z" level=error msg="middleware \"headers-default@kubernetescrd\" does not exist" entryPointName=websecure routerName=traefik-kubernetes-dashboard-ingress-578701c9f38d0d3a2640@kubernetescrd

```

I have created the middleware

```yaml
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: headers-default
  namespace: traefik

spec:
  headers:
    browserXssFilter: true
    contentTypeNosniff: true
    forceSTSHeader: true
    stsIncludeSubdomains: true
    stsPreload: true
    stsSeconds: 15552000
    customFrameOptionsValue: SAMEORIGIN

```

In the chart:

```yaml
...
...
providers:
  kubernetesCRD:
    enabled: true
    allowCrossNamespace: true
    allowExternalNameServices: false
    # ingressClass: traefik-internal
    # labelSelector: environment=production,method=traefik
    namespaces: []
    # - "default"
...
...

additionalArguments:
  - "--providers.kubernetesingress.ingressclass=traefik"
  - "--api.insecure=true"
  - "--serversTransport.insecureSkipVerify=true"
  - "--entrypoints.websecure.http.middlewares=headers-default@kubernetescrd"

...

```

```shell
~# kubectl -n traefik get middlewares.traefik.containo.us headers-default -o yaml
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"traefik.containo.us/v1alpha1","kind":"Middleware","metadata":{"annotations":{},"name":"headers-default","namespace":"traefik"},"spec":{"headers":{"browserXssFilter":true,"contentTypeNosniff":true,"customFrameOptionsValue":"SAMEORIGIN","forceSTSHeader":true,"stsIncludeSubdomains":true,"stsPreload":true,"stsSeconds":15552000}}}
  creationTimestamp: "2022-06-30T12:42:48Z"
  generation: 1
  name: headers-default
  namespace: traefik
  resourceVersion: "2341673"
  uid: 0338c872-5360-4077-8bdf-a82235718a9e
spec:
  headers:
    browserXssFilter: true
    contentTypeNosniff: true
    customFrameOptionsValue: SAMEORIGIN
    forceSTSHeader: true
    stsIncludeSubdomains: true
    stsPreload: true
    stsSeconds: 15552000

```

Traefik says he can't find the middleware headers-default@kubernetescrd.

Any idea please ? Thanks in advance for your help.
