Hacktoberfest: Update Linked List - print_reverse method (#2792)
* chore: update print_reverse helper method

Use a generator expression instead of slicing
`elements_list` to improve the space and time complexity
of `make_linked_list` to O(1) space and O(n) time
by avoiding the creation a shallow copy of `elements_list`.

* fix: add type checking and argument typing

Add argument typing to all methods in `print_reverse`

Add doctest to helper function `make_linked_list` and
basic edge case tests to `print_reverse`

* test: add `print_reverse` test

Fix doctest syntax and remove edge case tests that are covered
by typed arguments.

Add `print_reverse` test that expects the correct values are printed
out by adding a `test_print_reverse_output` helper function.

* format code
