5. Observe Input Action and Input Action Map names in the "Test Input (Script)" Component and compare them with names in TestInput.cs

Expected result: Public or Serialized Input Actions and Input Action Maps are shown with their names in the Inspector
Actual result: Public or Serialized Input Actions and Input Action Maps are shown without their names in the Inspector
