[3.x] Cannot use custom translators

[mikerockett]

I use a custom translator for Project Fluent, but this conflicts with the plugin:

InterNACHI\Modular\Plugins\TranslatorPlugin::__construct(): Argument #1 ($translator) must be of type Illuminate\Translation\Translator, Modules\Foundation\Translation\FluentTranslator given

Should TranslatorPlugin be updated to use the contract instead? Happy to open a PR, but only if it is the correct move (seems it would be).
