refactor: simplify Discord and Pushbullet alert message handling

The code changes in this commit refactor the way Discord and Pushbullet alert messages are handled. The previous implementation used separate variables for short information and no information scenarios, but now it uses a single variable for both cases. Additionally, the code now checks if the "alerturl" is empty instead of comparing it to a specific value.

These changes improve code readability and maintainability by reducing redundancy and simplifying conditional logic.
