to contents:read, so the excessive-permissions finding no longer
applies.

02:40 PM Ruby Revision f0f92435 (git): Use ubuntu-latest for macOS result jobs
- The result jobs in macOS workflows only check if other jobs failed
(just runs `exit 1`). They don't need macOS runners. Using
ubuntu-latest instead frees up macOS runner slots and starts faster
due to shorter queue times. -
- Move compilation steps from the heaviest jobs to the lightest to reduce
the critical path of the Compilations workflow.
