OptimizeLinqUsageFixer.UseIndexerLast code fix to use from the end Index (or at least propose both options ?)

[fforjan]

Following code :

var list = new List<int>() {...}
var last = list.Last();

would be refactored to

var list = new List<int>() {...}
var last = list[list.Count - 1];

it would be good to have a different fix :

var list = new List<int>() {...}
var last = list[^1];

Thanks for the suggestion! It's available in the latest version of the package (2.0.156).
