Updating perltidy (and other dependencies) in os-autoinst

When updating the dependecies.yaml file in os-autoinst, e.g. when you’d like to fix the outdated perltidy version in the repo the recommended workflow is to:

• Update dependencies.yaml
• Run make update-deps

This will update the cpanfile for you and you only need to make your changes in one single file (dependencies.yaml).
