Switch Currency and Locale API is not available

[rahulanand84]

In the API package, the switch-currency and switch-locale API's are missing the business logic to switch the currency and locale.

Go to "Packages/Webkul/API/Http/routes.php, you will see the routes for switching the currency and locale.

//Currency and Locale switcher
Route::get('switch-currency', 'CoreController@switchCurrency');

Route::get('switch-locale', 'CoreController@switchLocale');

but when you open the corecontroller, you will see no business logic to switch it.

public function switchCurrency()
    {
        return response()->json([]);
    }

public function switchLocale()
    {
        return response()->json([]);
    }

Currently, this is not supported that's why it is blank.

All these things will integrate when this enhancement is start,
https://github.com/bagisto/bagisto/issues/5143

In this, we will provide the API for the whole system.
