ci/request-reviews: move git calls out of get-code-owners

Browse Source 
This is just a refactor, no functional change. It is a preparation for a
future change, where `get-code-owners.sh` can be moved entirely into
eval/compare. This can only happen once we removed the remaining `gh
api` calls from it.
