Build Analysis and Helix Queue Insights checks block PRs without AzDO pipelines

[premun]

This PR only has a markdown change and did not kick off an AzDO run. The checks run, but since there's no AzDO build, the checks just sit there in a waiting state. dotnet/runtime#112885 (also see screenshot below)

Unsure if related, but a change was made to the status of the check recently: https://dnceng.visualstudio.com/internal/_git/dotnet-helix-service/pullrequest/49015
