Bug Description

Hi, I have a problem with running healthcheck middleware with a group:

package main

import (
	"github.com/gofiber/fiber/v2"
	"github.com/gofiber/fiber/v2/middleware/compress"
	"github.com/gofiber/fiber/v2/middleware/healthcheck"
	"github.com/gofiber/fiber/v2/middleware/recover"
)

func main() {
	app := fiber.New()

	app.Use(recover.New())
	app.Use(compress.New())

	group := app.Group("/app")
	group.Use(healthcheck.New())

	group.Get("/hello", func(c *fiber.Ctx) error {
		return c.SendString("Hello, World 👋!")
	})

	err := app.Listen(":5001")
	if err != nil {
		panic(err)
	}
}

• localhost:5001/app/livez doesn't work:

  curl localhost:5001/app/livez
  Cannot GET /app/livez

• localhost:5001/app/hello works

How to Reproduce

Steps to reproduce the behavior:

1. Run the main file above
2. Run curl localhost:5001/app/livez
3. It returns not found.

Expected Behavior

The endpoint should return HTTP 200

Fiber Version
