GHA uses yaml to define its actions, but there isn't a linter to ensure you're following the right format/expectations etc, and so we'll have catchable format issues like this.
Describe the solution you'd like
Look into available GHA linters like this. They're all 3rd party because GH doesn't support one yet. sad.
I also do my research on this and yeah I also can't found another linter than actionlint ref. github-reddit , but for starters, we can try to use actionlint.
