Subject: [PATCH] Adds a new entrypoing for the production jsx-runtime when
 using react-server condition. Currently the entrypoints are the same but in
 the future we will potentially change the implementation of the runtime in
 ways that can only be optimized for react-server constraints and we want to
 have the entrypoint aleady separated so environments using it will be pulling
 in the right version
