fix(ci): skip github.ref-gated jobs in ci_job_names (mc#958 mc#959)

Adds `github.ref` as a skip condition in ci_job_names(), matching the existing github.event_name skip. Jobs gated on github.ref (e.g. canvas-deploy-reminder: only runs on pushes to refs/heads/main) never execute in a PR context, so flagging them as missing from all-required.needs: is a false positive that triggers mc#958/mc#959.
