Next.js skips resolving `.d.ts` files. Rspack can achieve the same behavior by adding the `resolve.restrictions: [/^(?!.*\.d\.ts$).*$/]` configuration.

Following test cases will be passed:
- test/integration/typescript-paths/test/index.test.js
    - typescript paths default behavior should not resolve to .d.ts files
    - typescript paths without baseurl default behavior should not resolve to .d.ts files
- test/integration/typescript-workspaces-paths/packages/www/test/index.test.js
    - TypeScript Features default behavior should not resolve to .d.ts files
