0.85/0.86/0.87-nightly missing @react-native/jest-preset from devDependencies

[leotm]

Description

looks like every nightly and new rc release since

• Split out Jest preset to @react-native/jest-preset facebook/react-native#55169
• https://www.npmjs.com/package/react-native/v/0.85.0-nightly-20260217-db45c280e

ships with

• missing @react-native/jest-preset
• failing test script

we should merge

• Add @react-native/jest-preset to devDependencies #210

ideally before 0.87-stable to prevent future

• 0.86.0-rc.0/1 missing @react-native/jest-preset from devDependencies #219
  • Add @react-native/jest-preset to devDependencies #220
• 0.85.0-rc missing @react-native/jest-preset from devDependencies #211
  • 0.85.0-rc missing @react-native/jest-preset from devDependencies rn-diff-purge#91
  • Add @react-native/jest-preset to devDependencies #210
  • Add @react-native/jest-preset to devDependencies #212

then likely extend scripts\__tests__\package_json-test.js
to ensure all current @react-native/... scoped packages are present

i considered extending github.com/facebook/react-native/blob/main/.github/workflows/test-all.yml
since neither test_e2e_android_templateapp nor test_e2e_ios_templateapp cover yarn test
but a future breakage here causing all facebook/react-native PRs to break is a risk not worth it
