🚨 Issue number

Closes #3237

📝 What does this PR do?

The 'outputs' condition can be used only if the step or job has 'outputs'.
So the current post-commit workflow doesn't work and linting hasn't been done in a while.
It should be changed to use 'outcome'.

In addition to this, I also ran lint on .github/* because github-action-bot is not allowed to edit workflow files.
