Support multiple `TELEGRAM_CHAT_IDs`

Hi @mustafabayar

Thank you for a great bot, works like a charm 🤗

Unfortunately I'm not golang dev, so I can't contribute properly, but I have a feature request to support multiple chat ids.

It would be much convenient if my partner and I would receive the same messages together.

Thank you in advance 👍
