[mashehu]

now that we have a .yamllint.yml, we should also use it in a github action 🙂

Just get it to work and I'll approve ;-)

The problem is that it uses the old yamllint.yml config, which throws errors for the template files. I excluded them in this PR, but my understanding is that it first needs to be merged for the new rules to take effect. See: https://mashehu-tools-iljdr4oxkjs.ws-eu31.gitpod.io

YAML linting is failing

To keep the code consistent with lots of contributors, we run automated code consistency checks.
To fix this CI test, please run:

• Install yaml-lint
  • Install npm then install yaml-lint (npm install -g yaml-lint)
• Fix the markdown errors
  • Run the test locally: yamllint $(find . -type f -name "*.yml" -o -name "*.yaml") -c ./.yamllint.yml
  • Fix any reported errors in your YAML files

Once you push these changes the test should pass, and you can hide this comment 👍

We highly recommend setting up yaml-lint in your code editor so that this formatting is done automatically on save. Ask about it on Slack for help!

Thanks again for your contribution!
