Redirection error when using AddTrailingSlash middleware #108

Current Behavior

When AddTrainlingSlash middleware is used, the swagger route starts an infinite redirection loop resulting in ERR_TOO_MANY_REDIRECTS on the browser. It happens with both index.html and doc.json routes.

Steps to reproduce

  1. Follow the usage instructions and add the AddTrailingSlash middleware to the app:
package main

import (
	"github.com/labstack/echo/v4"
	"github.com/labstack/echo/v4/middleware"
	echoSwagger "github.com/swaggo/echo-swagger"
)

// @title Swagger Example API
// @version 1.0
// @description This is a sample server Petstore server.
// @termsOfService http://swagger.io/terms/

// @contact.name API Support
// @contact.url http://www.swagger.io/support
// @contact.email [email protected]

// @license.name Apache 2.0
// @license.url http://www.apache.org/licenses/LICENSE-2.0.html

// @host petstore.swagger.io
// @BasePath /v2
func main() {
	e := echo.New()

	e.Pre(middleware.AddTrailingSlash())

	e.GET("/swagger/*", echoSwagger.WrapHandler)

	e.Logger.Fatal(e.Start(":1323"))
}
