"<<<base-dir>>>" is not replaced with the real path

params:

'locale' => [
    'paths' => [
        dirname(__DIR__) . '/translations'
    ],
    'fallback' => 'en',
    'supported' => ['en']
],

config:

TranslatorInterface::class => new App\Factory\TranslatorFactory(
     $params['locale']['paths'],
    $params['locale']['fallback']
),

output:

'Yiisoft\\I18n\\TranslatorInterface' => unserialize("O:29:\"App\\Factory\\TranslatorFactory\":2:{s:48:\"\x00App\\Factory\\TranslatorFactory\x00translationsPaths\";a:1:{i:0;s:27:\"<<<base-dir>>>/translations\";}s:45:\"\x00App\\Factory\\TranslatorFactory\x00localeFallback\";s:2:\"en\";}"),
