fix(ci): volta build pra Cloud Build + bump Node 20 no webcomponent

- Reverte cd.yml pra Cloud Build (gcloud builds submit). Kaniko da PR #5
  quebra porque a imagem kaniko:debug não tem /bin/sleep no PATH e o
  act-runner usa entrypoint=["/bin/sleep","10800"] no container do job.
- Bump node:18 -> node:20 no stage do webcomponent (Vite >= 5 exige Node 20+).

Pré-requisito pro Cloud Build funcionar: SA gitea-cd precisa de
roles/cloudbuild.builds.editor + roles/serviceusage.serviceUsageConsumer.
