input: Write a python function to filter numbers greater than 5.
  assert filter_greater_than_5([3, 4, 6, 1, 8, 9]) == [3, 4, 1]
  assert filter_greater_than_5([10, 2, 5, 8, 3]) == [2, 5, 3]
  assert filter_greater_than_5([7, 8, 9, 10]) == []
output: def filter_greater_than_5(numbers):
      return [num for num in numbers if num <= 5]
