docs(api): fix syntax error in cherrypicking use case (#16100)

# Overview

Thanks to @alexjoel42 for [noticing this syntax
error](#15910 (comment))
in the cherrypicking use case. I think I tried to shift loading the
trash bin lower in the protocol and left it one line short of where it
needed to go.

## Test Plan and Hands on Testing

I simulated the whole code block, no modifications except indentation,
promise.
