Update react_on_rails to 16.2.0.beta.12

This update fixes the bin/dev pack generation failure that occurred with beta.11.

Key changes:
- Update react_on_rails gem from 16.2.0.beta.11 to 16.2.0.beta.12
- Update react-on-rails npm package to match (16.2.0-beta.12)
- Update json gem dependency from 2.14.1 to 2.16.0

The beta.12 release includes a fix for the Bundler auto-exec interception issue
where pack generation would fail with "Could not find command react_on_rails:generate_packs".
The fix wraps system("bundle", "exec", ...) calls with Bundler.with_unbundled_env to
prevent Bundler from intercepting subprocess calls.
