Proxmox - Discord notifications via Webhook

Note

If you have error 400 when sending the notification, that means that your message is too long, since Discord has a character limit of 2000. If you don't care about the logs, remove {{ escape message }} from the description field. Otherwise, seek another way to send notifications (i.e. via Cloudflare worker that truncates the description field).
