Sherman Hui 629848e372 [mypy] Fix type annotations in data_structures/binary_tree (#5518 )

* fix: fix mypy errors

Update binary_search_tree `arr` argument to be typed as a list
within `find_kth_smallest` function

Update return type of `merge_two_binary_trees` as both inputs can
be None which means that a None type value can be returned from
this function

* updating DIRECTORY.md
