deployctl is not able to read env secret in GitHub Action

deployctl not reading env secrets in GitHub Actions: in Deno Deploy project settings, change the git integration from 'Automatic' to 'GitHub Action'. That creates a 'Production' environment on your repo; create the DENO_DEPLOY_TOKEN secret in that environment. Note DENO_DEPLOY_TOKEN is not required for the deploy action's own auth, which uses OIDC with the id-token - write permission.
