Back out "[bundles] stop building legacy Paper renderer (#31429)"

Backs out the 2 related commits:
- f8f6e1a
- 6c0f37f

Since I only realized when syncing that we need the version of `react` and the legacy renderer to match.

While I investigate if there's anything we can do to work around that while preserving the legacy renderer, this unblocks the sync.
