[Feature Request] Add Support for Defining Examples for Non-Struct Response Types

[AminBhr]

Is your feature request related to a problem? Please describe.
When defining a success response that uses a non-struct type, such as a string, it is currently not possible to define an example for it. As a result, when viewing the Swagger UI, the response example section simply displays "string." This lack of customization reduces the clarity and usability of the API documentation. I would like a way to define examples for non-struct types in Swagger.

Describe the solution you'd like
Similar to how examples are defined for parameters (#1119 ), it would be great to have a similar format for responses. For example:
// @Success 201 {string} string "User created successfully" example("User created successfully")
With this implementation, the Swagger UI would display:

Additional context
The example content should be added to the response schema as per the OpenAPI v2 specification (reference here):

                "responses": {
                    "201": {
                        "description": "User created successfully",
                        "schema": {
                            "type": "string",
                            "example": "user created successfully"
                        },
                        "headers": {
                            "Location": {
                                "type": "string",
                                "description": "/users/{id}"
                            }
                        }
                    },
