Cannot find type definition file for 'jest'

Description

In a very minimal package declaring a dependency on react-native and the @react-native/typescript-config (such as a very simple library), extending the @react-native/typescript-config yields:

error TS2688: Cannot find type definition file for 'jest'.
  The file is in the program because:
    Entry point of type library 'jest' specified in compilerOptions

This happens because the tsconfig declares "types": ["jest"], while neither "react-native" nor "@react-native/typescript-config" declare a dependency on neither jest nor @types/jest.

I'd suggest moving the "types": ["jest"], to the template's tsconfig: https://github.com/react-native-community/template/blob/d2a0bee199b49611ee252dd5d7626f10a714bebd/template/tsconfig.json#L2 since that's the package bringing the jest dependency.

Steps to reproduce

Init a new package with this package.json

{
  "name": "react-native-ts-test",
  "private": true,
  "version": "0.1.0",
  "scripts": {
    "build": "tsc --noEmit"
  },
  "devDependencies": {
    "@react-native/typescript-config": "^0.81.1",
    "typescript": "^5.9.2"
  },
  "dependencies": {
    "react-native": "^0.81.1"
  }
}

and this tsconfig.json

{
  "extends": "@react-native/typescript-config",
  "include": ["src/index.ts"]
}

Run npx tsc --noEmit 💥

Screenshots and Videos

So sánh packages/typescript-config/tsconfig.json với các tệp template tsconfig.json và package.json được liên kết để hiểu các kiểu Jest được mong đợi ở đâu. Chạy npx tsc --noEmit trong trình tái hiện tối thiểu, sau đó xác minh rằng cấu hình hoạt động עבור một package không có các dependency của Jest và vẫn hỗ trợ thiết lập của template.
