Yaml Command Line Validator Tool

I want to use the yaml (.dockstore.yml) validation tool.

https://docs.dockstore.org/en/develop/advanced-topics/dockstore-cli/yaml-command-line-validator-tool.html#usage

dockstore yaml validate --path directory/of/.dockstore.yml

However, I don’t see the dockstore yaml command with the dockstore CLI on my Fedora Linux 36. Could you tell me how to use it? Thank you.

Edit: Perhaps the commit Feature/dock 2129/yaml file check (#161) · dockstore/dockstore-cli@033e5b7 · GitHub available from the version 1.13.0-rc.0 enables the dockstore yaml command?
