Suggestion: support translation autocomplete for Translator interface

[mfn]

Right now the following approaches support auto completion for translation:

• __(…)
• trans(…)
• app('translator')->get(…)
• when injecting \Illuminate\Translation\Translator directly, ->get(…) also works

The one thing which doesn't work is when injecting \Illuminate\Contracts\Translation\Translator, in this case it doesn't recognize it when calling ->get(…)

Thanks
