Tip for GitHub Runners Concurrency

The number of concurrent GitHub Action runners is determined by the plan of the GitHub Org to which the repository belongs, regardless of whether the repository is public. Even though GitHub Actions are unlimited and free for public repositories, they are still affected. Because of this, SWC uses the Enterprise plan.
If you're running a large open-source project and are having issues with GitHub Actions only running 20 jobs at a time, you can upgrade your plan to Team or Enterprise.
