Trigger generator tests when TypeScript files change

Fixes #2205

When TypeScript files in packages/react-on-rails/ change, the CI
change detector now triggers generator tests. This is important
because generator tests do a full build, which catches TypeScript
compilation errors that might otherwise slip through until
npm publish time.

The issue arose when PR #2125 changed TypeScript types but the
resulting compilation error wasn't caught until the release
script ran.
