docs: replace git_config to repo_config

Since this document was written, the built-in API has been updated a few times, but the document was left stale. Adjust to the current best practices by calling repo_config() on the repository instance the subcommand implementation receives as a parameter, instead of calling git_config() that used to be the common practice.
