[v5] New translations root

[afbora]

This PR …

This was a more complex problem than I expected (always 🙈). Because the system should be able to read, update and delete language variables both from the language file and from a custom root. It involves a breakage change, but I wanted to remove the code complexity by creating a separate LanguageTranslations object.

Fixes

• External language variables setup no longer works since K4's language views External language variables setup no longer works since K4's language views #6176

Features

• New translations root

$kirby = new Kirby([
    'roots' => [
        'translations' => __DIR__ . '/site/translations',
    ],
]);

Breaking changes

Now $language->translations() returns LanguageTranslations object instead array. Use $language->translations()->toArray().

Ready?

• Unit tests for fixed bug/feature
• In-code documentation (wherever needed)
• Tests and checks all pass

For review team

• Add changes to release notes draft in Notion
• Add to website docs release checklist (if needed)

Great solution to move the logic to a separate class. 👍
A few things I noticed while skimming through the changes:

Excited for this, thanks! Will this include the possibility to add translations (e.g. for the panel) even if the language does not have a content language assigned to it? Some of my pages are German only, but should still have English translations for the panel.

@tobimori In your case; multilingual is not enabled for the frontend, but you want to add translations (for example for blueprint labels) for users in different languages using the panel. Do I understand correctly?

Multilingual is enabled, but the languages in the panel might differ from the languages in the frontend.
Let's say I have de and en in the frontend, but I want to add a french translation for my field labels etc. as well.

Currently, I have a translations directory and load yaml files from a plugin. (https://github.com/tobimori/kirby-baukasten/blob/main/site/plugins/project-extended/index.php#L20)

If there is no FR language (so fr.php language file), unfortunately it will not load custom FR translations. It will only load the translation files for existing languages from a custom root.
