chore(ci): unignore test/correctness so the agent-pin manager runs

config:recommended (via :ignoreModulesAndTests) ignores **/test/**, and
ignored paths are dropped before any manager extracts from them -- so the
custom Agent-pin manager never saw test/correctness/cases/*/config.yaml
and the OTLP baseline image pins would still drift (caught in review).

Override ignorePaths to reproduce the inherited defaults minus **/test/**,
and explicitly re-ignore test/antithesis/** (the only test/ files built-in
managers recognize: a Dockerfile and a docker-compose) so behavior there
is unchanged.
