Clarify sort example (#802)

For the .vb file (.cs file handled in #801) - I added an additional "Jody" to demonstrate how the sorting function handles duplicate values, and updated the sample unsorted and sorted output to demonstrate how the duplication is handled.

Fixes dotnet/dotnet-api-docs#1875
