Check Translations from Filament 2 to Filament 3

If you used translations in v2, the old keys might be placed in a new location in v3.

Publish translations and find the new keys.

php artisan vendor:publish --tag=filament-panels-translations

// Filament v2:
Checkbox::make('remember')
    ->label(__('filament::login.fields.remember.label')),
 
// Filament v3:
Checkbox::make('remember')
    ->translateLabel('filament-panels::pages.auth.login.form.remember.label'),
