laravel_version() is deprecated

[abdelhamiderrahmouni]

👋 Hi, thanks for the awesome packages you provide.
I am using the arcanedev/laravel-settings and when run composer dump-autoload i get the following deprecation warning.

Illuminate\Foundation\ComposerScripts::postAutoloadDump
Deprecation Notice: laravel_version(): Implicitly marking parameter $version as nullable is deprecated, the explicit nullable type must be used instead in ~/project/vendor/arcanedev/support/helpers.php:13
