Fix TypeError in runRealtimeReport after upgrading

[jaroslavstefanec]

This PR fixes a TypeError that occurs after upgrading to propably version 5.5.2 (reference to PR #535).

When calling runRealtimeReport(), the method expects an argument of type Google\Analytics\Data\V1beta\RunRealtimeReportResponse, but an array is being passed instead. This results in the following error:

TypeError: Spatie\Analytics\AnalyticsClient::runRealtimeReport(): Return value must be of type Google\Analytics\Data\V1beta\RunRealtimeReportResponse, Google\Analytics\Data\V1beta\RunReportResponse returned, array given (reference: #515 (reply in thread))

This fix will ensure that the request argument passed to runRealtimeReport() is correctly instantiated instantiated and that the time range is adjusted, as using a date range is no longer possible in real-time reports.

use Spatie\Analytics\Facades\Analytics;
use Spatie\Analytics\Period;

// number of active users in the last 30 minutes which is visible in GA4 -> reports -> realtime overview
$period = Period::create(Carbon::now()->subMinutes(29), Carbon::now());
Analytics::getRealtime(period: $period, metrics: ['activeUsers']);
