The env-list fix got every test green on the runner for the first time --
37 of 37, the JUnit publish included -- and the job then failed in the
artifact upload: upload-artifact@v4 speaks GitHub's v2 artifact service and
hard-refuses any host that is not github.com ("not currently supported on
GHES"). Gitea implements the v3 artifact API, so the three upload steps --
coverage, the benchmark tables, the valgrind logs -- pin to v3.
