🐛 [Bug]: BodyParser doesn't parse form values to map

[sujit-baniya]

Bug Description

When trying to parse a form data to map, I'm getting an error schema: interface must be a pointer to struct

How to Reproduce

package main

import (
	"bytes"
	"errors"
	"net/url"
	"reflect"
	
	"github.com/gofiber/fiber/v2"
)

func main() {
	app := fiber.New()
	
	app.Post("/", func(ctx *fiber.Ctx) error {
		var data map[string]any
		err := ctx.BodyParser(&data)
		if err != nil {
			return err
		}
		return ctx.JSON(data)
	})
	app.Listen(":8081")
}

curl -X POST http://localhost:8081 \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "method=GET&path=/user/:id&handlerMsg=User Profile"

Expected Behavior

It should have worked with map, struct or slice

var data map[string]any

Maybe you have change var data map[string]any to var data map[string]interface{}
