Bug: cli does not detect error in v2 config

Feedback & Bug Reports

The following is invalid config in v2 (but valid if the version was 2.1 as commands is a 2.1 feature)

version: 2

commands:
  install_terraform:
    steps:
      - run:
          name: Install Terraform
          command: sudo ./.circleci/install-terraform.sh
jobs:
  validate_terraform:
    docker:
      - image: circleci/node:8.10.0
    steps:
      - install_terraform
      - run: apk add --update make
      - run: make validate

workflows:
  version: 2
  deploy_cdn:
    jobs:
      - validate_terraform

In ci I get the following error, as expected

Build-agent version 1.0.11727-b0960fc9 (2019-05-23T02:12:54+0000)
Configuration errors: 1 error occurred:

* In step 2 definition: step type "install_terraform" is not a valid type

But the cli circleci config validate does not surface this error
