bug(Dialog): Explicit injector does not work

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

Hey, I recently updated to v14 just for the newly added feature of the Dialog - the explicit injector, but it does not seem to work. I might be doing something wrong or misunderstood the new feature (to provide an `Injector` without having to provide a `ViewContainerRef`).

### Reproduction

Steps to reproduce:
Check out https://stackblitz.com/edit/angular-ozdqwy?file=src%2Fapp%2Fdialog-overview-example.ts (hope this lives long enough)
**OR**
1. Open the dialog example https://stackblitz.com/run?file=src/app/dialog-overview-example.ts
2. Add some service `@Injectable()
export class SomeService {
test = 123;
}`
3. Create an injector `const myInjector = Injector.create({
providers: [{ provide: SomeService }]
});`
4. Pass the injector `injector: myInjector`` to ``this.dialog.open`
5. Require the service `public someService: SomeService` in `DialogOverviewExampleDialog`'s constructor

### Expected Behavior

`SomeService` gets provided to `DialogOverviewExampleDialog`

### Actual Behavior

```
ERROR NullInjectorError: R3InjectorError(AppModule)[SomeService -> SomeService -> SomeService]:
NullInjectorError: No provider for SomeService!

```

### Environment

Angular CLI: 14.0.5
Angular: 14.0.5
Angular Material: 14.0.4
Node: 16.13.0
Package Manager: npm 8.1.0
OS: win32 x64

### Additional info
I glanced into the source code and I think the injector from the config is taken into account only when creating/attaching the
container:
https://github.com/angular/components/blob/c28bbdeb51c31cbd1f5e06528ef4d21b1650e4a8/src/cdk/dialog/dialog.ts#L224
but not when creating/attaching the actual content component:
https://github.com/angular/components/blob/c28bbdeb51c31cbd1f5e06528ef4d21b1650e4a8/src/cdk/dialog/dialog.ts#L311
and it seems that from a DI point of view, the implementation does not tie the content's Injector with the container's Injector. Again, I might be wrong.

Thanks!

Commencez par src/cdk/dialog/dialog.ts aux lignes référencées 224 et 311, puis reproduisez le problème à l’aide de l’exemple StackBlitz lié et de sa configuration explicite d’Injector. La tâche est terminée lorsque le fournisseur SomeService fourni via l’Injector explicite est disponible pour DialogOverviewExampleDialog sans qu’une NullInjectorError ne se produise.
