Refactor createSliceReducerBuilder transform file

  - Eliminated `@ts-ignore` directives to improve TypeScript compliance.
  - Configured `lineTerminator` in `.toSource.options` for consistent end-of-line across platforms, overriding `jscodeshift`'s default OS-specific EOL.
  - Refactored `__fixtures__` files to contain slightly more realistic and practical examples.
