This is a followup to https://github.com/TheAlgorithms/Python/pull/4973#issuecomment-933117382
As per given suggestion, I've added type hints to certain methods that don't have them. I have also added documentation and example doctests as a usage example for (most of) those that don't have them.
I have also added another test case following the previous test case's format. I noticed that the existing test case from previous pull request might be redundant with the ones I've made, so I decided to create a specific situation where the linked list would have to keep different kinds of data types for each node, in `test_singly_linked_list_2` test function.
Some minor changes in strings has been done to keep things consistent with other parts of the document. If it is undesirable, please let me know.

* 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
