Make sure you can install plugin with no direct input

It is working fine in a internal project running on Gitlab CI.

The pipeline is running a composer image and adding xulieta and json plugin like this:

xulieta:
  stage: test
  image: composer:2.2.6
  script:
    - composer require codelicia/xulieta
    - composer require codelicia/xulieta-json
    - vendor/bin/xulieta check:erromeu -v .

May we add a section on the README, on how to add it to the gitlab and github CI? /cc @EHER

@malukenho That is a good idea. Maybe a path in the repo:

examples/.github/workflow/xulieta.yaml examples/.gitlab-ci.yam examples/global-composer-install.sh

Let's do it in another issue. 👍🏻
