Refactor logger class for improved readability

The dependency on the 'util' module's format function has been removed from logger.ts. This change simplifies the main functions such as info(), warning(), error(), and debug(). Previously, these functions were using the format function to construct the console.log string. Now, the string is constructed natively using template literals, thus improving code readability and maintainability. This modification should not affect the application's functionality, it's purely an improvement in the code structure.
