Describe the bug
After following this guide to upgrade to NativeScript 8.2.0 from 8.1.5, now when I run "npm install" it gives these warnings:

MacBook-Pro:UI justintoth$ npm install
npm WARN EBADENGINE Unsupported engine {
npm WARN EBADENGINE   package: '@eslint/eslintrc@1.2.1',
npm WARN EBADENGINE   required: { node: '^12.22.0 || ^14.17.0 || >=16.0.0' },
npm WARN EBADENGINE   current: { node: 'v14.16.0', npm: '8.3.1' }
npm WARN EBADENGINE }

npm WARN EBADENGINE   current: { node: 'v14.16.0', npm: '8.3.1' }
npm WARN EBADENGINE }
npm WARN EBADENGINE ...

Worse, when trying to build it throws errors about "fs":

Here is the full build log: https://gist.github.com/justintoth/d8fde7b79e45df5f2f3310cf56d04edd

Commencez par reproduire npm install et le build NativeScript avec les versions signalées de NativeScript, Angular, Node et npm. Suivez la chaîne d’importation depuis src/app/shared/services/analytics.service.ts via @nativescript/firebase-crashlytics et examinez le journal de build complet lié pour identifier l’échec de dépendance. C’est terminé lorsque le projet signalé s’installe et se build sans les erreurs de résolution de modules affichées.
