Date pickers are not localized

[F0urchette]

Description

During initialization, the application loads the language defined in the browser. But this loading does not modify the browser locale, which is english by default. Because of this, the date pickers are in english

Steps to reproduce

• Set browser language to french
• Log in the application
• Go to Configuration/Edit sessions
• Add a session
• Click on the date button

Actual result

Weekdays and month names are in english

Expected result

Weekdays and month names are in french

Hints

Add this provider in app.module.ts :

{
      provide: LOCALE_ID,
      useFactory: (translateService: TranslateService) => translateService.currentLang,
      deps: [TranslateService]
}

Notes

This will load the locale according to the browser's language, but only at the application's startup. Changing the language on the application will therefore have no effect on the date pickers
