[Bug] Resolver in app.ts no longer compiles with the stable types

[boris-petrov]

🐞 Describe the Bug

Check the repro.

app/app.ts:9:3 - error TS2416: Property 'Resolver' in type 'App' is not assignable to the same property in base type 'Application'.
  Type 'typeof Resolver' is not assignable to type 'ResolverClass'.
    The types returned by 'create(...)' are incompatible between these types.
      Property 'resolve' is missing in type 'CoreObject' but required in type 'Resolver'.

9   Resolver = Resolver;
    ~~~~~~~~

  node_modules/ember-source/types/stable/@ember/-internals/owner/index.d.ts:413:5
    413     resolve: (name: string) => Factory<object> | object | undefined;
            ~~~~~~~
    'resolve' is declared here.

app/app.ts:12:18 - error TS2345: Argument of type 'typeof App' is not assignable to parameter of type 'typeof Engine'.
  Construct signature return types 'App' and 'Engine' are incompatible.
    The types of 'Resolver' are incompatible between these types.
      Type 'typeof Resolver' is not assignable to type 'ResolverClass'.

                    ~~~

🔬 Minimal Reproduction

Repo.

Run npm install and then ./node_modules/.bin/tsc.

😕 Actual Behavior

Type error on Resolver.

🤔 Expected Behavior

No error. Removing the last commit (which upgrades Ember) and rerunning npm install and then tsc will remove the errors.

🌍 Environment

• Ember: 5.1.0
• Node.js/npm: 20.3.1/9.7.2
• OS: Linux
• Browser: N/A

Thanks for reporting! I confirmed this as well; a brand new ember new --typescript app doesn't type check on this specific point!

Will be fixed by #20489.
