fix: forward thread_id to Telegram adapter + update send_typing signatures

Part 2 of thread_id forum topic fix: add metadata param to
send_voice, send_image, send_animation, send_typing in Telegram
adapter and pass message_thread_id to all Bot API calls. Update
send_typing signature in Discord, Slack, WhatsApp, HomeAssistant
for compatibility.

Based on the fix proposed by @Bitstreamono in PR #656.
