chore(Next.js sync): open draft PRs immediately (#82424)

Before:
Cron runs would open a Draft PR if they happened to run before
deployment tests finished. Once deployment tests completed, the system
would either open a PR and immediately close it (if tests failed) or
open it as ready for review (if tests passed).

After:
Both cron runs and new releases will open Draft PRs. Once deployment
tests run and pass, these PRs will be marked as ready for review. If
tests fail, the PRs remain as drafts.
