[JENKINS-62737] Kubernetes secret doesn't show up in Jenkins /credentials/ page

I have the following secret in Kubernetes cluster:

```

apiVersion: v1

kind: Secret

metadata:

    name: mysecret

    namespace:

labels:

    credential.sync.jenkins.openshift.io: 'true'

type: Opaque

data:

    username:

    password:

```

I have tried to restart the jenkins pod in my k8s cluster. However, the secret does not show up in the jenkins /credentials/ page.

According to https://jenkinsci.github.io/kubernetes-credentials-provider-plugin/ I have also tried the following secret label:

```

apiVersion: v1

kind: Secret

metadata:

    name: mysecret

    namespace:

labels:

    "jenkins.io/credentials-type": "usernamePassword"

type: Opaque

data:

    username:

    password:

```

And accessing it in my jenkins pipeline Jenkinsfile using the following snippet:

```

withCredentials([usernamePassword(credentialsId: 'nexus', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD')]) { withCredentials([usernamePassword(credentialsId: 'mysecret', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD')])

{   

    echo PASSWORD     

     echo USERNAME

}

```

result in the following error:

`ERROR: Could not find credentials entry with ID 'mysecret'`
