The currently recommended best practice for Github action workflows is to set top-level permissions to read only. And if the job uses the automatic `GITHUB_TOKEN`, fine-grained permissions for each job based on the job's requirements should also be added.
All existing workflows in the repository now have top-level read only permission blocks.
Only the `scorecard` workflow currently requires additional job level permissions and the minimum set of permissions were already present for the job.
