HTTP Errors are not properly handled (v 1.3.0 and 1.4.0)

[nicolaslaunaySO]

With SDK version 1.3.0 and 1.4.0, HTTP errors like the 404 error are not properly returned, and give an SDK error instead.

Steps to reproduce

package main

import (
	"context"
	"log"
	"os"

	novugo "github.com/novuhq/novu-go"
)

func main() {
	apiKey := os.Getenv("NOVU_API_KEY")
	client := novugo.New(novugo.WithSecurity(apiKey))

	_, err := client.Workflows.Get(context.Background(), "non-existent-workflow", nil, nil)
	if err != nil {
		log.Fatal(err)
	}
}

Expected :

"404 error" or equivalent

Actual :

error reading response body: file already closed``
