I think we should update the validation calling logic too 👀
At L200, in case c.spec could not be cast to validator type, we ignore it and return no error. In case LambdaDeployementSpec, CloudrunDeploymentSpec, TerraformDeploymentSpec does not satisfy validator interface, error should be raised.

@khanhtc1202 Right. Let me update that part.
