Buildkite retry all

Retry all failed jobs in Buildkite

This extension is for Buildkite user only. Are you tired to click Retry on every failed step on your Buildkite build? Well, I do. Especially, when most of them were just flaky tests. That's why I made this codemod to add a button to Retry all failed steps at once. Just one click and move away. Let Buildkite continue doing what it's designed to do.
