chore: CXSPA-7900 Ajust schematics to enable option in fresh apps

[pawelfras]

PR contains a small adjustment to schematics that enables avoidCachingErrors optimization option in a fresh application to avoid tech debt.

QA steps:

• build and deploy Spartacus packages locally:
  npx ts-node ./tools/schematics/testing.ts in the SPA root folder`
• create new app npx @angular/cli@17 new my-app --standalone=false --style=scss --routing=false
• go to the project's directory and install Spartacus from local packages:
  npx @angular/cli@17 add @spartacus/schematics@latest --ssr --baseUrl="https://40.76.109.9:9002"
• check in server.ts whether avoidCachingErrors has been added:

  const ngExpressEngine = NgExpressEngineDecorator.get(engine, {
    avoidCachingErrors: true, // takes effect only when cache is enabled
  });
  

closes CXSPA-7900
