Add ror_components wrapper for ReScript component

The react_on_rails gem auto-generates component registration by scanning
for ror_components/ subdirectories. When we migrated to .res.js, we
deleted the old ror_components wrapper, breaking auto-registration.

Created a thin wrapper that imports the .res.js file and re-exports it
for react_on_rails to discover and register.

This fixes the CI error:
"Could not find component registered with name RescriptShow"
