fix: userId issue in logout mutation

[rushikeshacharya]

Content (작업 내용) 📝

• Issue:
  • The userLogOut function expects a userId of type number as a parameter, but the logout mutation is currently passing the entire User object instead.
• Fix:
  • Modify the logout mutation to pass userData.id (the user ID) to the userLogOut function instead of the entire User object.
