Ensure require-hook env is set properly on deploy (#48902)

This ensures we set the pre-bundled react env variable early enough when
in a deploy environment as otherwise incorrect react versions could be
initialized with app directory.

Test deployment with fix can be seen here
https://metadata-dynamic-lsbqdamud-vtest314-ijjk-testing.vercel.app/dynamic/test

This re-adds the patch we were doing before
b5f7f84#diff-90d1d5f446bdf243be25cc4ea2295a9c91508859d655e51d5ec4a3562d3a24d9

No additional tests were added here as existing e2e deploy tests were
failing without this.
