improve language stats rounding: - Add tests (I had to omit some edge cases as the current method is non-determistic in some cases, due to random order of map access). - Document the algorithm used. - Lower the amount of calculations that need to be done. - Because of the aforementioned non-determistic don't use stable sort and instead regular sort. better sorting for `RepositoryList`: - Add testing - Use `slices.Sortfunc` instead of `sort.Sort`. - Remove the methods needed for `sort.Sort`. better git tag sorter: - Use `slices.SortFunc` instead of `sort.Sort`. - Remove `tagSorter` and its related methods. - Added testing.
