Update auto-close-pr.yml#160

changes i tried was, Variable Naming: I renamed the step ID from `check_employee` to `check_member`. This makes it clearer that the purpose is to check if the user is a member of the organization, not just an employee. Error Handling: I switched from using `console.log` to `console.error` for logging errors. This is a better practice because it helps highlight issues more effectively when reviewing logs. Consistent Return Values: I ensured that the output from the membership check is always a string. This makes it easier to compare values later in the workflow, reducing potential confusion.
