Migrate to bot middlewares

[javiyt]

Use telebot middlewares https://github.com/tucnak/telebot/releases/tag/v3.0.0

// Global-scoped middleware:
b.Use(middleware.Logger()) // logs every incoming handled event
b.Use(middleware.AutoRespond()) // automatically responds to every callback

// Group-scoped middleware:
adminOnly := b.Group()
adminOnly.Use(middleware.Whitelist(adminIDs...))
adminOnly.Handle("/ban", onBan)
adminOnly.Handle("/kick", onKick)

// Handler-scoped middleware:
b.Handle(tele.OnText, onText, middleware.IgnoreVia())
