Add Jaro and Jaro-Winkler Algorithms to String Module (implemented in #22701)

[Wajinn]

V's string module has the Levenshtein distance algorithm (here). In many cases where people would be looking at Levenshtein, they may also want to consider Jaro and Jaro-Winkler.

V already has examples of both at Rosetta Code, Jaro and Jaro-Winkler.
