[Bug]: php documentation change capitalization

[marcinmisiak]

What's on your mind?

In doc PHP composer you have: OneSignal/onesignal-php-api

by error show after composer u: require.OneSignal/onesignal-php-api is invalid, it should not contain uppercase characters. Please use onesignal/onesignal-php-api instead.

So change in doc to : onesignal/onesignal-php-api
