Re-issue IDE OAuth token that allows to push GitHub workflows

IDE

(See recipe for Windows below)

I've literally just come across this problem when trying to use IntelliJ to push to a branch that contains a GitHub Action workflow (YAML file in .github/workflows). I didn't find existing resources on the Internet very helpful, so I hope this will help you fix it too.

TL;DR: Generate a new Personal Access Token with the workflow scope enabled in GitHub and configure your application to use that.

/*
I came up with a single pass O(n) sort algorithm I call StalinSort.
You iterate down the list of elements checking if they're in order.
Any element which is out of order is eliminated.
At the end you have a sorted list.
