ci: remove Docker container from release workflow

Remove container: node from the release job to avoid Docker Hub rate
limits on self-hosted runners. Uses actions/setup-node@v4 instead,
matching the pattern already applied in plugin-ci.yaml (PR#14).

Changes:
- Remove container: node:${{ inputs.node-version }}
- Add setup-node@v4 step with npm cache after checkout
- Remove apt-get install step (jq, curl, git already on runner)
- Remove manual GitHub CLI install step (gh already on runner)
