ci(repo): keep snapi baseline cache warm and bump snapi pin

- drop the paths: filter on the push trigger so publish-baseline runs on every main/release-branch commit, keeping the cache that check-api restores hot.
- bump SNAPI_PACKAGE to the current snapi main HEAD; the previous pin predates subpath snapshot support, so changes on subpath exports (e.g. @clerk/backend/webhooks) were never detected.
