@oJshua - can you update the references under docs/, clap-utils/src/input_validators.rs, and cli-config/src/config.rs as well. There may be a couple other references in the repo as well.

These updates should be backported to v1.6 once we're ready to make this switch to api. as well please

@mvines Do you know if the doc translations (zh) get updated dynamically somewhere or I do I need to commit changes there as well?

I think a human does it, somehow. In this case I think you can update directly
