add commit hash to S3 object identifier for artifacts on S3 (#8161)

In future we may want to run periodic tests on dedicated cloud instances
that are not GitHub action runners.
To allow these to download artifact binaries for a specific commit hash
we want to make the search by commit hash possible and prefix the S3
objects with
`artifacts/${GITHUB_SHA}/${GITHUB_RUN_ID}/${GITHUB_RUN_ATTEMPT}`
