Apply PR 2039 changes: modernize generator config and workflow (#2040)

## Summary

Applies key changes from PR 2039 to modernize generator configuration
and workflow updates:

- **examples.yml:133** - Changed `yalc publish` to `yarn yalc publish`
for consistency
- **react_on_rails.rb.tt** - Enabled `build_test_command`,
`auto_load_bundle`, and `components_subdirectory` config options
- **shakapacker_examples.rake** - Added `REACT_ON_RAILS_SKIP_VALIDATION`
wrapper for generator commands and `generate_packs` step

These changes align with the modernization efforts to improve generator
reliability and configuration defaults.

+#### Changed
+
+- **Generator Configuration Modernization**: Updated the generator to enable recommended configurations by default for new applications:
+
+  - `config.build_test_command` is now uncommented and set to `"RAILS_ENV=test bin/shakapacker"` by default, enabling automatic asset building during tests for better integration test reliability
+  - `config.auto_load_bundle = true` is now set by default, enabling automatic loading of component bundles
+  - `config.components_subdirectory = "ror_components"` is now set by default, organizing React components in a dedicated subdirectory
+
+  **Note:** These changes only affect newly generated applications. Existing applications are unaffected and do not need to make any changes. If you want to adopt these settings in an existing app, you can manually add them to your `config/initializers/react_on_rails.rb` file.
