Address PR review nitpicks and style suggestions

1. Refactor apply_minimum_versions into focused helper methods:
   - update_react_dependencies: Updates React and React-DOM versions
   - update_shakapacker_dependency: Updates Shakapacker in deps or devDeps
   - update_package_json_versions: Parses JSON and coordinates updates
   - update_gemfile_versions: Updates Gemfile with pinned version
   - apply_minimum_versions: Orchestrates both file updates

   This eliminates all RuboCop metric disables and improves testability.

2. Improve error message to include full package.json path instead of
   just the directory, making debugging easier.

3. Fix task description symmetry - both latest and minimum version
   task descriptions now specify exact versions for clarity:
   - latest: "React 19, Shakapacker 9.4.0"
   - minimum: "React 18, Shakapacker 8.2.0"
