fix: tool result in examples

[MegaGrindStone]

Motivation and Context

In both examples, the tools returns the parameter name instead the value of the parameter. No matter what client input as Name, the tool result always returns: Hi greet.

This PR fixes it by returning the Name from the arguments.
