refactor: update alert messages in lgsm/modules/alert.sh

- Updated the alert messages for when the game server is stopped, started, restarted, and when an LinuxGSM update is received.
- Changed the wording to use "has been" instead of "has" for consistency.
- Added a mention that the server has been restarted after receiving an LinuxGSM update.
