Corrected color inconsistencies

[cyberlytics]

Changed color code of Bucket Sort, Radix Sort, and Counting Sort from green to yellow, to be in sync with the bigocheatsheet.com color code specs for O(n)

(Obviously this should also impact your beautiful poster variant.)

Without this correction you have a serious inconsistency with the (correct) yellow codings of Timsort, Bubble Sort, Insertion Sort and Cubesort in their Best Case scenario. They actualy perform better than Bucket Sort, Radix Sort, and Counting Sort but currently have the worse color.

I can understand that there was the intention to mark Bucket Sort, Radix Sort, and Counting Sort as the best algorithms? But the current version is still colorwise broken, both the table and the poster.
