Subject: [PATCH] verify_exercises_in_docker: avoid version mismatch

The versions are pinned in the test runner. Hopefully they are not too
outdated, but they can easily be a few patch versions behind. If the
solution directory contains a lock file, these requirements often won't
be satisfied in the test runner.
