ci: exclude verification.json from the inline profile validation

The matrix runner records its verdicts in profiles/verification.json, which
is not a build profile; the Makefile target and test_core already skipped
it, but the workflow's own inline validation loop did not, so every push
failed validating verdict records against the profile schema.
