feat: add memory game and a games folder (TheAlgorithms#2471)

* feat: add memory game and a games folder

* fix: `clang-tidy` warnings (hopefully)

* fix: use `random_shuffle`

`random_shuffle` was removed in C++17, however, we're using C++11 here, so there should be no harm.

* updating DIRECTORY.md

* clang-format and clang-tidy fixes for 8cd0a77

* fix: remove repeated `random` header

* clang-format and clang-tidy fixes for 0278688

* fix: Windows build errors

* fix: CI warnings (hopefully)

* fix: CI warnings

* fix: (finally) CI warnings

* fix: wrong parameter name

* fix: yet another attempt to fix CI
