Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.google-analytics.com
  • Triggering command: ng build @manekinekko/angular-web-bluetooth --configuration production (dns block)
  • Triggering command: ng test @manekinekko/angular-web-bluetooth (dns block)
  • Triggering command: ng build angular-web-bluetooth-starter --configuration production (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list

Updated the CI workflow to use Node.js 22.x and upgraded GitHub Actions to latest versions (checkout@v4, setup-node@v4). Also updated .nvmrc to match. This should resolve the CI build failures with Angular v20. (20d9ac5)

@copilot Importing "setup-jest.js" directly is deprecated. The file "setup-jest.js" will be removed in the future.
Please use "setupZoneTestEnv" function instead. Example:

    // setup-jest.ts
    import { setupZoneTestEnv } from 'jest-preset-angular/setup-env/zone';

    setupZoneTestEnv();

Fixed the Jest setup deprecation warning by replacing the deprecated import 'jest-preset-angular/setup-jest' with the new setupZoneTestEnv() function in both test-setup.ts files. The tests now run without deprecation warnings. (ff5bb79)
