Documentation update for initializing TranslateService

[tanieltari]

Hey!
In the documentation you recommend to initialize service in AppComponent constructor for standalone components.
I would propose to update this section to use provideAppInitializer instead.
Example:

import { provideTranslateService, TranslateService } from "@ngx-translate/core";

bootstrapApplication(App, {
  providers: [
    ...,
    provideTranslateService({
     defaultLanguage: 'en'
    }),
    provideAppInitializer(() => {
      const translate = inject(TranslateService);
      translate.addLangs(['de', 'en']);
      translate.setDefaultLang('en');
      translate.use('en');
    }),
  ],
});
