[BUG] Custom .Error does not work on schemas other than @Required

[ktalebian]

Describe the bug

Here is a request object:

class MyRequest {
  @Property()
  @MinLength(10).Error('Title must be at least 10 characters long')
  title: string;
}

And the controller

@Controller("/")
export class HelloWorldController {
  @Inject()
  myService: MyService;

  @Post("/body")
  @Returns(200, String)
  async cache(@BodyParams() body: MyRequest) {
    return 'done';
  }
}

I expect to get a custom error message when I make curl localhost:8083/body -XPOST -H "Content-Type: application/json" -d '{"title":"short"}' but still get the generic message:

{
  "name": "AJV_VALIDATION_ERROR",
  "message": "Bad request on parameter \"request.body\".\nMyRequest.title must NOT have fewer than 10 characters. Given value: \"foo\"",
  "status": 400,
  "errors": [
    {
      "instancePath": "/title",
      "schemaPath": "#/properties/title/minLength",
      "keyword": "minLength",
      "params": {
        "limit": 10
      },
      "message": "must NOT have fewer than 10 characters",
      "data": "foo",
      "modelName": "MyRequest",
      "dataPath": ".title",
      "requestPath": "body"
    }
  ],
}

I tried a few different decorators. It looks like only the @Required decorator works.

To Reproduce

1. Clone https://github.com/ktalebian/tsed-bug
2. npm i
3. npm start
4. curl localhost:8083/body -XPOST -H "Content-Type: application/json" -d '{"prop1":"asd"}' | jq .

Expected behavior

Expected to see Title must be at least 10 characters long message.
