Deprecation of legacy Dependabot job runners

[github-product-roadmap]

Summary

With this deprecation, Dependabot will no longer run on legacy infrastructure, and instead all Dependabot jobs will run in GitHub Actions. Customers will be migrated automatically with no need for manual intervention on their part, and Dependabot jobs will not be interrupted.

Intended Outcome

This will allow customers greater insight into Dependabot jobs and logs, and allow them to leverage the GitHub Actions APIs to observe Dependabot jobs or use the result of those jobs to kick off other parts of their CI/CD. They will also be able to set up Dependabot to run on self-hosted runners in order to allow Dependabot to access private registries that are not available to the public internet.

How will it work?

Dependabot will continue to function as always, but will be running its jobs in GitHub Actions.
