input: Write a function to filter numbers greater than 5 using lambda function.
  assert filter_greater_than_5([1, 2, 3, 4, 5, 6, 7, 8])==[6, 7, 8]
  assert filter_greater_than_5([10, 4, 2, 8, 6])==[10, 8, 6]
  assert filter_greater_than_5([3, 4, 5])==[]
output: def filter_greater_than_5(numbers):
      return list(filter(lambda x: x > 5, numbers))
