ci(release): switch npm publish to OIDC trusted publishing

NPM_TOKEN secret was never configured, so tag-triggered releases failed
with ENEEDAUTH. Auth now uses npm trusted publishing (configured on
npmjs.com for this repo + release.yaml):

- drop NODE_AUTH_TOKEN env (empty token would shadow OIDC auth)
- upgrade npm to >= 11.5.1 (trusted publishing requirement; Node 22 bundles 10.x)
- bump checkout/setup-node to v5 ahead of the June 16 Node 20 runner cutoff
