feat(channel): add support for Telegram Business bots (#10181) (#11663)

Added support for Telegram Business bots. Telegram webhooks from such bots include the business_message field, which we transform into a standard message for Chatwoot. This PR also modifies how we handle replies, attachments, and image uploads when working with Telegram Business bots.
