This PR is to remove duplicate Rosetta Code sorting problems that exist in other parts of the curriculum. Here are the problems that are being removed:
* Sorting algorithms/Bubble sort
* Sorting algorithms/Counting sort
* Sorting algorithms/Heapsort
* Sorting algorithms/Insertion sort
* Sorting algorithms/Merge sort
* Sorting algorithms/Quicksort
* Sorting algorithms/Radix sort
* Sorting algorithms/Selection sort
This PR only removes the challenges in English. I could remove the other languages in this PR, or in another PR.
