feat: add conditional printing of alert messages

This commit adds conditional statements to only print alert messages if the corresponding alerts are turned on. This improves the readability of the output by only displaying relevant information.

- Added conditionals for Discord, Email, Gotify, IFTTT, Pushbullet, Pushover, Rocketchat, Slack, and Telegram alerts
- Only prints alert messages if the corresponding alerts are turned on
