Update message.go

which is used to filter preformatted code entities based on their programming language. The filter will return true if it finds a preformatted code entity with the specified language, otherwise false.

here is the example to how to use this

package main

import (
    "log"

    "github.com/veerpratap6870/gotgbot"
    "github.com/veerpratap6870/gotgbot/filters"
)

func main() {
    bot, err := gotgbot.NewBot("BOT_TOKEN", &gotgbot.BotOpts{})
    if err != nil {
        log.Fatal(err)
    }

    // Example of MessageEntityPre filter
    offset := 0
    length := 10
    language := "python"
    filter := filters.MessageEntityPre(offset, length, language)

    bot.Dispatcher.AddHandler(filter, func(ctx *gotgbot.CallbackContext) {
        // You can access the message that matched the filter using ctx.EffectiveMessage
        ctx.Reply("Message matches the criteria.")
    })

    err = bot.StartPolling()
    if err != nil {
        log.Fatal(err)
    }
}

@TG-BOTSNETWORK While I appreciate the example, CI is still failing on this PR, which makes me doubt that any of it has been tested

Closing because filter is too niche to make sense in the library
