fix: Improved error handling and input validation for project name in…

[ursulabauer]

Description

I’ve added a validation to ensure that the second argument (project name) is provided via the command line. If the project name is missing, the script will terminate with an appropriate error message, making it easier for users to understand what went wrong.

Additionally, I’ve wrapped the file reading and writing operations in a try...catch block. This will allow the script to catch and display more detailed error messages when there are issues interacting with files.

Finally, I’ve included a success message that confirms the file update has been successfully completed.
