Jwt middleware not using fiber ErrorHandler

[Andrflor]

Hello,
I was wondering if it's and intended behavior...
(Code may be better to explain)

The default error handler is written

	if cfg.ErrorHandler == nil {
		cfg.ErrorHandler = func(c *fiber.Ctx, err error) error {
			if err.Error() == "Missing or malformed JWT" {
				return c.Status(fiber.StatusBadRequest).SendString("Missing or malformed JWT")
			} else {
				return c.Status(fiber.StatusUnauthorized).SendString("Invalid or expired JWT")
			}
		}
	}

This way the error is not processed trough the app error handler
Should it not be that way to be processed by any application level error handler by default?

	if cfg.ErrorHandler == nil {
		cfg.ErrorHandler = func(c *fiber.Ctx, err error) error {
			if err.Error() == "Missing or malformed JWT" {
				return fiber.NewError(fiber.StatusBadRequest, "Missing or malformed JWT")
			} else {
				return fiber.NewError(fiber.StatusUnauthorized, "Invalid or expired JWT")
			}
		}
	}

Not sure if i am clear enough 😅

Just to add some information – BasicAuth middleware not using that approach: https://github.com/gofiber/fiber/blob/9dd39c0e55376b68b368a82f181446da8d96962f/middleware/basicauth/config.go#L94

But for me it makes sense... Will continue digging...
