Describe the bug

The Kratos Go client (version 1.1.0) fails to correctly unmarshal the JSON response into the LoginFlow object.
This happens because it defines the state field as a required property, which is not provided within the response from the Kratos instance (version 1.1.0)
An easy fix for it would be to remove the state field as a required property, like on this fork.

Reproducing the bug

When initiating a native login flow using something like:

kratosClient := client.NewAPIClient(configuration)
loginFlow, _, err := kratosClient.FrontendAPI.CreateNativeLoginFlow(context.Background()).Execute()
if err != nil {
	fmt.Println(err)
}

the error occurs.

Inspecting the response using curl to initiate the flow:

curl -X GET \                                          
    -H 'Content-Type: application-json' \
    127.0.0.1:4433/self-service/login/api

shows that there is no state field being returned at this stage of the flow:
