5feab57 set runs-on to actrunner-debian-aarch64-bohr, which is the
display name of the bohr runner, not a label. Gitea Actions matches
runs-on against labels — the actual labels on bohr are debian-trixie,
aarch64, debian-aarch64. Using the runner-name as runs-on leaves the
job unrouted (no matching runner).
