[v5] Plugin translation not applied in backend

[distantnative]

I encountered a weird regression in Retour:

Translation that I apply in the backend (via I18n::translate) are not translated correctly anymore;

v4:

v5:

Interestingly, translation that are resolved in the frontend ({{ $t() }}) seem to work/unaffected.

I encountered a similar issue when running commands. the license label build failed when retrieving license.status.active.label because the translation array for en local is still empty.

As far as I can tell from debugging the call stack the needed AppTranslations trait defining the i18n via closure has not been called yet when kirby encounters the Kirby::plugin() from within the plugins index.php file.

kirby/src/Cms/App.php

Line 141 in 6adc851

$this->i18n();

@bnomei how do you use it in your plugin?

[bnomei]

in calling a command from the cli is how i encountered the issue. you should be able to replicate it.
