Upcoming breaking change for GitHub Actions: Removal of larger hosted runners from self-hosted API

Upcoming changes to GitHub Actions runner APIs

The orgs/{org}/actions/runners API currently shows self-hosted runners and individual larger hosted runner instances. As of July 3rd, 2025, we will no longer show larger hosted runner instances. At that point, the orgs/{org}/actions/runners API will only show self-hosted runners. This change will make the API behavior match our existing documentation.
