Update auto-close-pr.yml

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.
