Missing tags Property in the API Response of User-Defined Federated Authenticators

[Shenali-SJ]

Description

API responses for user-defined federated authenticator operations do not contain the tags property.

On par with the default behavior, tags should be included in each federated authenticator.

Default Behavior:

    "federatedAuthenticators": {
        "defaultAuthenticatorId": "************************",
        "authenticators": [
            {
                "authenticatorId": "************************",
                "name": "GoogleOIDCAuthenticator",
                "isEnabled": true,
                "definedBy": "SYSTEM",
                "tags": [
                    "Social-Login",
                    "APIAuth"
                ],
                "self": "/api/server/v1/identity-providers/************************/federated-authenticators/************************"
            }
        ]
    }

Faulty Behavior:

    "federatedAuthenticators": {
        "defaultAuthenticatorId": "************************",
        "authenticators": [
            {
                "authenticatorId": "************************",
                "name": "customFedAuthenticator",
                "isEnabled": true,
                "definedBy": "USER",
                "self": "/api/server/v1/identity-providers/************************/federated-authenticators/************************"
            }
        ]
    }

Steps to Reproduce

1. Create a user-defined federated authenticator.
2. Check the API response.

Observe that the tags property is not included in the API response.

Environment Details (with versions)
