[CI] Fix cache not saving (#5213)

#### Commits in this PR
1. [CI] Fix cache not saving
    
    Re-using the output of the cache restore step was recommended by the
`actons/cache` docs, but it doesn't work here because we actually start
from a clean cache when we run save so there is no output available to
    read.
    
    The annoyances of testing in the PR but main being a different
    environment.
2. Bump macOS timeout
