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":

首先，使用回報的 NativeScript、Angular、Node 和 npm 版本重現 npm install 和 NativeScript 建置。追蹤從 src/app/shared/services/analytics.service.ts 經由 @nativescript/firebase-crashlytics 的匯入鏈，並檢查連結的完整建置記錄，以找出相依性失敗。回報的專案能夠安裝和建置，且不再出現所示的模組解析錯誤，即表示完成。
