Revert: remove trailing newline (no-op nudge does not fix stale translation)

The CLI publish pipeline reads every translation file fresh on each run
and does not deduplicate by content hash, so a trailing-newline change
does not influence whether the file gets re-uploaded. The publish-docs
job has been running successfully on every merge to main since #5348
landed without the corrected link being reflected in the live Chinese
page \`/learn/zh/sdks/deep-dives/readme\`. The bug is platform-side,
not source-side.
