Not closing any issue with this PR.

Quote from the GitHub Blog:

Starting today, administrators using Github.com accounts can enable their repositories and/or organizations to run Dependabot updates jobs as a GitHub Actions workflow using both hosted and self-hosted runners. Running Dependabot does not count towards GitHub Actions minutes–meaning that using Dependabot continues to be free for everyone.
