pages: remove the boot smoke test from the release pipeline

It was failing CI on real but slow/flaky-under-node-timeout per-lib boot
issues that don't reflect whether the actual browser deploy works. Bad
bundles are caught by the hands-on deep functional test pass (AGENTS.md
§10.7) instead, run against the native driver before a lib is committed.
