(#21614) Include /v2 in metrics end-point examples

Previously we weren't adding the /v2 to the examples show in this document.
While it is true there is no difference between v1 & v2 in this case, we
should keep the convention to avoid confusion, and to make clear the end-point
is part of the versioned structure.
